Yeah,
I had Atari, from Atari 2600, 5200, Atari 600XL, 65XE to 130XE.
For my taste, Atari Hardware was made of better quality than Commodore (at least XL Hardware series). In thats time i was C=64/128 too (i am still user)..But the thing was Atari never had the same succes like Commodore.
About 16Bit, 32bit, 64bit Atari computers, i never had. But i know about becouse have friends they were Atari users, with ST, Mega STE, Falcon, Lynx..
For me Amiga was much better than thats machines.. for the time, many things not have comparision.
For now i still have my Atari 2600 from 1978!! Wood Front style (i had over 200 Cartridges!)
Anyway its sad nowdays not exist in the market more Brands like Atari or Commodore..
