Your purchase budget is a big player.
I think if I was looking for a reasonable sole-owned tourer with good IFR capability, and fair range and performance, I'd start looking perhaps at a Grumman Tiger or a C182, which are pretty economical. Personally I prefer the ergonomics and handling of the AA5 over either the PA28 or the C182, and I really like having my own door!
Without a doubt the TBs will offer a nicer and more capable aeroplane than any of these, but the purchase cost will also be substantially greater.
You will, ultimately, get what you can afford to buy.
