Trading recipes

I've narrowed my search for the best system design/backtesting software down to Wealth Lab vs. Trading Recipes. As far as the basic bread and butter, (i.e., design & test of entry/exit) they seem to be about equal. It's really just a matter of taste. However, I'm looking for an advantage in one of the following categories.
Does anyone out there have insight into:

Which has better bet-sizing testing ability?

Which has better support from 1) designer and 2) community?

Which is easier to use?

Which is easier to mesh with data sources?

Other advantages/disadvantages?

Thanks Much
