Tube amps and speaker ohms

In your opinion , do push pull amps work better with 8 ohms or 4 ohms. .I am under the impression the lower the ohms, the more power is demanded from the amp....Another question, are there low powered SET amps ,and high power SET amps?
I'm looking at a 40 watt 845 tube amp for my 8 ohm, 89 db speaker.. just cked the Thor has a 86 db W18 midwoofers(2 per cabinet) and a 88 db tweeter. Will an 845 amp rated 40 watts be able to drive the 86/88 db speaker? With authority, bass, mids, highs, in dynamic sound stage? Synergy? Or poor match?

This has been a very interesting thread.......

Having said that, my Primaluna PL2 with KT88's, 40wpc, has no trouble driving the Proac D15's, 88db, to louder than WAF levels in our 15 x 30 x 10 room.

Bartokfan,
Did you ever bias those tubes?.....
