This playlists consists of amp sim research and development 
These amps are based. on real amplifiers powered by tubes etc

The lists starts with the closest settings by the manufacture
Then custom IRs from the actual real amps are added as speakers
Then finally a Master Bus with Plugin Alliance BAXEQ

This soundcloud account is dedicated to dialing up the crunchiest Marshall sweet spots in  amp/sims, sometimes adding the bx_yellow drive aka Boss SD1.

I tested these sims and amps with 1 Riff and some tracks so you can all hear the sims character after dealing back into the sweet spots.

As of August 2022 the top ten tier over many plugs are:
1 Howard Benson Tonality
2 Kuassa Vermilion
3 JST Toneforge Guilty Pleasure
4 Kuassa Caliburn
5 Kuassa Creme
6 Softube 1959 Plexi
7 Softube Murder One
8 Softube JCM800 2203
9 Plugin Alliance FUCHS II Train
10 Softube Marshall Jubilee

The rest are sims that have great crunch as well as other tone sim attributes 
-JST Toneforge Ben Bruce
-JST Toneforge Menace 
-JST Toneforge Jeff Loomis,
-Softube Softube Marshall KK 
-scuffhamamps S-Gear
-Plugin Alliance Fuchs Overdrive Supreme50
-Plugin Alliance Suhr PT100
-Plugin Alliance Friedman BE100

-Plugin Alliance Friedman DS40
-Mercurial Spark
-Neural DSP Cali, Tone King
-Nembrini BG Extacy
-Nembrini MRH810v2
-Overloud  TH-U 

The rest offer some variations of other amps well but did not sound any where near as close to the amps listed above.
-Amplitube
-PRS
-Peavy
-Positive Grid

I have not tested blue cats and a number of upcoming competitive plugins yet.
