Hey
@Jo-, I've got a 2013 Paul's Guitar, 2019 SSH and a 2020 ME V (pickup config very similar to the 35th Anni, minus the pot switch and middle single coil) so hopefully some of what I've discovered (and obviously my own highly subjective opinions) will be of some help.
2013 Paul's Guitar
Of the 3, the single coil tones on the 2013 Paul's Guitar are the least 'strat-ty', and more 'thick woody P90', and my favorite of the 3 guitars when coil split. It's got the characteristics of a good P90 (comparing this against my Collings 290 with P-90 Throbaks), but slightly less spanky and trebly, which IMO is good and a very unique voicing. I've heard nothing like these pickups when split, pretty magical.
Now, I haven't tried the new 2018 Paul's Guitar, however I believe the pickups are the same as those on the 2020 Modern Eagle V.
2020 Modern Eagle V
The single coil tones on these when split are
very realistic, but just a touch a smidge more woody, and slightly thicker in the lower mids vs. against my Fender CS Wildwood '63 Strat. Sounds quite different from the 2013 Paul's Guitar. But single coil note definition is very present, and just a hair less jangly than the aforementioned strat but much more than the Paul's Guitar.
2 and 4 positions with pickups split are great, very convincing as single coils. However when splitting from humbuckers to single coils, there is a noticeable volume difference (less of a difference in the 2013 Paul's Guitar).
Full humbucking tones between the Paul's Guitar and the ME V are quite similar, very tight, slight push in the mids, sweet overtones all around, very responsive, and feel of the string bounce is immediate.
There is witchcraft in these pickups.
2019 Special Semi-Hollow
Overall tones are quite different from the PG and ME V.
I found the response to be more sponge-y, overtones aren't as crisp, but coil taps are quite convincing (but moreso than the PG, but less than the ME V). Less touch-sensitive, less 'lively' than my Hollowbody II.
Bridge humbuckers with drive into a cooking amp is quite amazing, but in other pickup positions, while not disappointing, wouldn't be what I reach out to this guitar for.
The obvious recommendation is to get all 3, but if I were in your position (and with my preferences), I'd definitely wanna check out the newest Paul's Guitar.
