Bluehost is one of the very old providers we have tried. It used to be very good initially and due to some bad experiences with uptime, we had moved to another host. Recently we found that Bluehost has now an India site that will accept payments in INR and hence you don't have to pay any dollar conversion fee.

They have also introduced some new concepts like Dev Cloud and Cloud sites. Cloud Sites boasts of a higher performance than regular shared hosting. Even Reseleller club also sells similar hosting in partnership with bluehost we believe.

I have been using siteground for some time now and I was overall happy with their services, even though there has been some bad time as well. But the good part was they were ready to do things to change the bad to good.
