If you want small and portable the Jubilee is the one to get...way more saturated than any stock 2203/4. The EQ is very responsive-unlike any other Marshall made other than a modded one. It takes one boost pedal to take it into Metal territory..whereas the 2203/4 needs 2 boosts IMO.
If you can swing the Fortin that's a beast for sure...but you could grab the 2555x Jub reissue or a vintage Jubilee for the money the Fortin costs and still have cash left over. The 2555x has a great loop, and you can use any 2 pairs of octal tubes in it, bias points are on the outside of the chassis. 2 6550s with 2 EL34s, or 2 6L6 with 2 KT88s etc. The Jubilee is darker than your typical Marshall; but can get bright enough if you need it.
