Anyone have honest opinion of Jolida amps?

I think there is some snobbery concerning the Jolida. Its not a $40K set of Jadis' but, rather, a fine piece of listening equipment. I love this amp. It is smooth, warm, reliable, and tweakable.
I replaced the signal tubes with (2) Ken-Rad VT-231 (military 6sn7) and replaced the single 12ax7 with an FAA 5751 (military 12ax7 with 70% gain). The 5751 works fine for me and I don't notice the lower gain. For power tubes I use Svet. 6550s.

This amp has nice tight bass and sweet (not sticky) mids and highs. The lack of glare using a moderate CDP (Marantz 67se with Art DI/O)is simply delightful (as in I enjoy the music).

By the way, since the Jolida integrated amps have the volume control before the signal tubes, the Art DI/O 6v output can run straight to the amp. inputs without a resistor and without overloading the amp's front end. Actually, the DI/O acts as gain pumper.

The Jolida looks good, sounds wonderful, is reliable and is fun to play with. Anything "better" costs an order of magnitude more.

I thought the original question was whether the Jolida was a viable intro to tube amplification. You obviously like solid state. Goody for you. So do I. But that's why I have three systems, two SS, one Jolida based tube.

Your comparison of Sealelectronic DIY kits and Jolida is comparing apple sauce to orange juice. It simply is not a valid (or logical) comparison.

Dakajoba, a Jolida is a great way to get introduced to tubes. You may like em, you may not. I have nothing at all against a Dynaco ST-70, but an updated version and tube preamp is going to set you back at least as far as a Jolida without any substantial advantage (and no warranty).
