Best hosting for my site ..
 

Hi one of my site is getting 20,000+ hits/day, I am using hostgator sharing hosting. I dont think this hosting plan can handle more traffic then this. Suggest me which hosting plan should I choose ??

They have doubtful reputation, so I would recommend you to look at much better one that has really good reputation.
It is Stratus4.com - these guys know how to keep everything working and running efficiently. Try their 15% OFF CODE: S415OFF

I must say, you are receiving good amount of traffic and any shared host won't allow you to host this website in their shared server. I will recommend you Linux VPS with minimum of 1 GB RAM for your website.

I could recommend you AccuWebHosting.com as the excellent Linux and VPS Hosting provider. AccuWebHosting.com provides exhaustive web resources at most affordable prices in all plans. AccuWebHosting holds the widest range of services starting from Super Cheap shared Hosting to High RAM Dedicated server. Also, your requirements are easily fulfilled in Linux VPS Earth at just $12.99 /month.

Better you go with VPS Plan, Plenty of hosting companies and plans are there, Just check this, listed top 5 VPS hosting companies and their features are there-http://www.ihostingreviews.in/top-5-vps-hosting

Taking into account your needs, I can highly recommend you to contact Swissns.ch as these guys are professionals. They will find the best hosting fit for your specific needs.

They keep their platforms spam/malware free and therefore have no issues with blocked servers, slow services and so on.

hi Guys Thanks for you kind suggestion will try one of them...

When it comes to hosting I prefer to deal with time-tested and trusted brands like these 3 web hosts:
1) Stratus4.com
2) Kvchosting.com
3) Dreamhost.com
They offer feature-rich and affordable hosting deals and good customer support, so you will find out the availability of their systems administrators and send them a support ticket and see how fast they respond.

It looks like your site is most busiest site so I would suggest you to opt cloud hosting or vps hosting as bandwidth resources will be more on vps or vm than shared hosting.

Use Godaddy. It is cheaper and reliable. But I cannot ensure the service of it because I didn't use godaddy earlier.

what about hawhost

I'd like to say Smart-web-host.com is the perfect hosting to get any web hosting solutions at low rates. They have stable network, professional support and high performance of servers.

Good website you added on your signature, nice one!!
