I own two MIJ Aria TAs, which are their thinline semis. One is a TA-30 (a genuine semi-acoustic) from 1986 and which was my first decent electric; the other is a TA-STD (a semi-solid, ie has the 335-esque centre block), the model below the top of the range TA-DLX (I actually preferred it to the DLX as I don't like gold hardware!). Both play incredibly well, although I will concede that now I'm aware the pick-ups could be better, especially on the TA-30.
However, owning these guitars has left me with a soft spot for Arias. I don't think I've ever played a bad one, even if the design didn't thrill me (eg pointy metal type guitars), and I generally try them if I encounter one. I had a 12-string acoustic from their Sandpiper range for a couple of years recently and that was a great, easy playing instrument. The PEs are well worth checking out; they're like a Les Paul's sexy sister!
What I can't tell you is which would be better in your particular case, as I've not got much Greco experience. They have a good reputation, as I'm sure you know. But I do love Arias...their prices are generally pretty low on eBay and I can't imagine you being disappointed with one.
