I bought an Aria pro 335 lookalike (10 or 15 years ago.) Looked good to me in the shop and I fell for it without really deliberating, but after returning home and spending a few hours with it I recognised the error of my way. I remember the neck was very flexible and it sounded very thin plugged in, and with poor sustain.
I can believe that, just like Gibsons (and probably almost any other marque,) they are not all the same, but the one I bought was quite a nice ornament. I took it back within a week to get my money back, which is a story in itself.
Some years later I was fortunate enough to afford a custom shop 335 which, in my opinion, sounds beautiful, plays beautifully and is aesthetically beautiful. It is very well made and very well finished; essentially a professional quality instrument that should appreciate in value. I play it mainly through my Cornford Hellcat or an old WEM Westminster and, to my ears, is good for Jazz, blues and rock sounds.
I would add two caveats to anyone in the market for a Gibson 335: 1. They are overpriced (which you will have to swallow if you really want one) and 2. They are not all made equally (be prepared to travel and play many before handing over any money for a 335.)
That said, the Aria cost about £300 iirc and the Gibson was nearly £3000. Make what you will of that but I agree with randythoades that there is simply no comparison between the two.
I won't be buying another Aria instrument, and rather than spend any money hotrodding one, I'd save up a bit of money and trade/swap in your aria for something else. I don't think you'd have to spend anywhere near Gibson prices to get a really great Jazz sound that will trounce that Aria.
I hope this isn't considered dredging and I'd imagine the OP has moved on (everything moves so fast nowadays to me) but having owned both, I felt like sharing my experience.
