Haven't actually played the Dorado, but from clips and description its alot darker (modern) sounding, I prefer the mid grind and Marshally flavor of the plex. more of a thrash type tone, you should p.m. LDM, she has my old Makoplex and a Dorado Mak2, she can fill you in better than I.
i have a dorado. yes it is def a darker amp but you can def get the mids and highs to shine through. i love the amp. the only way i would sell it is if i was desperate for cash.
The Makoplex does the hot-rodded Marshall tone. It uses EL34's. Great sounding amp. My friend actually described it as a darker SLO. The Mak2 Dorado is more modern. It uses 6550's in the power section. It is a tight dry amp which you may love or hate IMO. Lot's of gain, more low end...Killer amp but probably not for everyone.
I really want a Promod or a Quickrod also. I love my Nitro. It too is kind of dry in comparison to say an Uber or my Rocca Ultra. I boost so that cures the issue for me with both the Nitro and the Mak2 Dorado.
Both builders are super cool too so you have a tough decision ahead of you. For "da brootz", I would probably go Mak2 Dorado over the Promod but again, either would do it well.
