I haven't used the latest version but last year I was using the system and found it quite an easy way to get quick professional looking reports done for clients.  No errors with things not balancing and when adding accounts to the ledger it is easy to add these in the system too.

I don't see how it would matter what accounting system you use, we have a couple of different systems clients use but all the reports we produce are consistent, and we can maintain this even when we change systems (which we did for one client a couple of months ago).

I must say, I think it is quite good value when you consider the amount of time that can go into building a template, then always adjusting the formula for each new change.  I leave it up to these guys so I don't even need to think about the template itself. So far, if I have ever wanted a change to the template I ask them and it's been done!

I must also admit, I no longer use the template myself but it is used for most management accounts for our clients as I actually outsource this also to these guys and not yet had a problem... just makes my life easier.
