I switched over to 20i around 6mths ago, migrating a few of my client's sites over to test the VPS service. I have absolutely no regrets, the products and support from all departments be it accounts or technical has brilliant. and I will be migrating the rest of my clients over with the coming weeks and today I have ordered another VPS.
I have been involved in hosting on various levels for the last 20 years and so far I can say without a doubt they have been the best. I hope their growth does not change any of the above.
