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?

Hiend2: I use 45 watts a side from a CJ CAV50 to drive my 86 dB Vandy 2Ce Sigs in a moderately sized room and I have very little trouble hitting my comfort zone of 80 dB in my listening position about 10 ft from them.

I don't know where you get that opinion unless you listen to Metallica at concert levels (120 dB), then it all makes sense.
