"Better" is very subjective. Better for what?

Too many people make the mistake of thinking that more WordPress plugins must be better, when in fact they just bog the site down with unneeded cruft.

contact form 7
all in one SEO or SEO by YOAST
wp total cache
Akismet

I'd be more inclined to think of what you think your website neeeds and then search for a plugin to fill the need. The more plugins you have though, the slower your website will perform, so I wouldn't go plugin crazy. Good content will make the site what you need it to be.

But I do agree with most people above, a good contact form, SEO Plugins (All in One or Yoast , Google XML Sitemaps) will help with Search Engine Traffic. To speed up your website there's also w3 Total Cache.

Which type of plugins are you looking? SEO yoast is best for overall

I have check the suggestions and really believe that Jeffery's post is the best one. However I would advise you to pay attention to Limit Login Attempts. When it comes to protection I personally believe it is good enough.

Of course you should not install all possible extensions in order to improve the performance of your website or add more and more features. Bear in mind that each extension extends the database ( adds new tables to the database ) of your website and this way increases the changes for a given Mysql query to become slow. The outcome of slow query might be a restriction if your account is situated on a shared hosting machine or performance issues if you are on VPS or Dedicated server.

Of course the final decision depends on you Good Luck!

Install whatever plugin that you really NEED but not WANT because too much of plugin could lower down your site performance.

It depends what kind of Wordpress plugins you want. By the way, Jeffery has written lots of good plugins.

Just like many other warriors have stated, adding too many plugins isn't healthy for your wordpress website. Another thing you need to take into consideration is your servers specification. If your webpage is hogging a lot of the resources, it will impact your webpage load time and also your web host may charge you extra or shut your website down. I had this issue occur when I was running an e-commerce website using Magento. As multiple customers entered the page, it starts to bog down the server.

Figure out what plugins or features you need. Don't look at others page and add just anything. Most times, you will realize that you don't need them.

nah install what you need, not what you want, too much plugin will slow your site down...

Even you have more plugins installed is ok just don't keep activated everything that you don't regularly use to keep speed going ok.

The goal should always be to use as few plugins as possible.

Why?
- security
- speed
- resources use - CPU, RAM, Mysql queries

More plugins means more security holes/threats to worry about.
More plugins slows down the site in almost all cases, even with caching.

And host will kick you off shared plans if the site is a resource hog. You'll have to move to a higher grade plan like VPS or semi-dedicated (higher shared) hosting. It costs more, and the VPS route takes much more knowledge on your part.

Note: You should be using a good host anyway, as they're less likely to suspend your site for using plugins. And picking a good host DOES NOT mean Hostgator/Bluehost/EIG! Look instead to Arvixe, Site5, Veerotech or Stablehost.

that is depends on you which words press plugin want to install many new plugin are available on wp.

yes agreed use less plugin to keep wordpress secured.

i recommend this plugin as "IS A MUST"
contact form -7 - contact form
wp-pagenavi - for pagination if youre using custom theme
nextgen-gallery - for media manager
== dont bloat your site with too much plugin it has also a downside...

Wow, I thought I had some good suggestions then saw Jeff's post. Just look at those....what a great list.

No matter what plugin you use. always check the impact on your page speed. Some plugins not running inside your hosting server. they calling so many external resources, which may slow down your site.

Tip! Always Delete the plugins your not using. Don't make them inactive and keep on the server. It will slow down your site again.

WordPress › Advanced post slider « WordPress Plugins
Here is a new one for me and it does something I have been trying to do for ages. Thing is it takes a little work and ingenuity because I have configured it to do what it is designed to do, but I worked it into opt-forms. Specifically, you can rotate different images in a single opt-in form. This is perfect if you have a website that gives away more than one ebook and you want to display the different ecovers in a small area. The ebook ecovers will rotate within the small space while your optin form remains stationary.

To make it work install it and select template #3. Also, in your post or widget create the standard WordPress (WP) tables with the WP editor. Last, insert the plugin shortcode into the table cell. After ages of trying different plugins I find that this one works well with shortcodes inside tables/rows/cells.

So if you want to scale up your visitor's experience and if you want a targeted list this may be for you.

Jeffery 100% :-)

P.S. The plugin is free from wordpress.org.
