Plenty decent to do any SMD stuff which you can possibly use without THP.
8/8 rules work just fine. There is no significant difference to
photoprocess in my experience, if both done at home. Of course you can get
a bit better with photoplotters and stuff, but that's not generally
homebrew any more. Also, you soon run into underetching problems with both
processes anyway.

No. It makes no difference at all, some even had worse results.

The quality of TT can easily be what one would call "flawless", but the
board will still look homebrew. Because of THP and soldermask. Milling is
worse though, in terms of looks.
