I didn't use the Malcolm Puddle Technique, but rather gave several coats of Future to the model (allowing the coats to dry) before applying decals. This was because I dread silvering. For the decals, I used Mirco Set followed by several applications of Micro Sol, and then sprayed future over it again after the decals were set and dry.
Having said that, I did use the Malcolm Puddle Technique on my Hs 123 last year, and comparing the two, I'd say that the MPT worked best--the decals look absolutely painted on. (Hmm, but wait, those were aftermarket decals supplied by Claus Dam.)
The reason I didn't go for the MPT with the Spitfire was my concern about the deep 'n wide panel lines; I thought that Micro Sol would melt the decals into the lines better. After the fact, this did not seem to happen so well. Also, while the carrier film didn't silver, if you look very closely you can still see the (very clear) decal film. You can see here how the decal film still masks some panel lines around the "Z":

(I suppose could go back and try and retouch those lines, but I really want to avoid giving them any more prominence than they have.)
Anyway, I still think that the best approach is mask and paint, but failing that, on my current build (Hurricane Mk I), I think I'm going to go back to Malcolm's Puddle Technique.
