Newsup vs Newspaperex

I’m using the Newsup theme now, the free version. I did pay for Newsup Pro, but currently I’m running an A2 Hosting hosted business website on www.ads-software.com platform. So I can’t run any of the Pro themes, even when I pay for them, because www.ads-software.com only runs Free themes. Or so I’ve heard. I’m thinking about switching my main business site, now on www.ads-software.com and hosted by A2 Hosting company, to WordPress.com like my other two business websites. They are each on WordPress.com and are not hosted on A2 Hosting at all.

What do you think? I am wondering. Should I make the big move, stop hosting my main business site at https://www.rainbowriting.com over at A2 Hosting through www.ads-software.com and switch it all over to just the WordPress.com platform, for a business site at $300 per year? The price is likely to go up, but it would still be much cheaper than the $70 per month I’m paying A2 Hosting to host it over there, and the additional payments made to www.ads-software.com for the domain name renewal etc. Well, I’d only need to host the site at WordPress.com if I did make the switch.

www.ads-software.com gives me some cool perks. But maybe I’d be better off hosting all three websites at only WordPress.com. Anyone here have enough expertise to give the right kind of advice?
