Oh what a minefield....I'll have tread carefully here for fear of offending people, but here are my thoughts; There is no such thing as a 'one size fits all' amp - it all comes down to compromise and what you are prepared to sacrifice in quality in return for functions and features. There are two factors at play here, depth of quality and breadth of features. The very best amps that have ever been built tend to be 'one trick ponies' ie Fender Champ, Marshall Plexi and Bluesbreaker, Fender Twin Reverb, Mesa Boogie dual rectifier etc. Trouble is, all these amps are chosen by their owners because of their individual charictaristics and are very much a matter of choice based on the individuals genre and playing style.
The trouble with an amp which is a jack of all trades invariable is a lack of ability to shine in any one direction - 'Amp modeling' is all well and good but only if you want to sound like a Boogie one minute and a Plexi the next. Sure they will get you fairly near to both, but will still not really sound like either.
Every amp purchase should be approached as if it was your last, and great thought should be put into the decision before you buy; Is it the right sound? Is it practical to maintain?, Can I carry it around?, Will it have a resale value if I find I can't live with it?
OK, so what are the options currently?
Fender Champ XD is a good bet, as is the Champion. Both are semi modelling with the bonus of valve power stages. Low powered, but ideal for home use. For pure tube sound, Vox, Marshall, VHT and Blackstar all do great little heads. Ibanez do a great head based on a fifteen watt power stage driven by a tube screamer circuit which is pretty exciting. Heads are always a good bet as you can drive a little 1 x 12 at home or a miced up 4 x 12 in the studio or on stage.
As far as features go, I would advise to go for the the least possible - save perhaps a reverb. Everything else you can do from pedals and can chop and change as you wish in the future.
Also of course, budget has to be consideration in this - no budget? Then go for a Cornford, Cornell or LazyJ !! Alternativley look for the higher end stuff second hand via Ebay or Gumtree where ther are bargains to be had.
There again....you could enquire via this forum and who knows, you might find someone who has an amazing 5 watt Blackstar head and cab currently for sale
