It depends if you want to be able to use the boost by itself or not
With the first one the effects can be used individually or simultaneously. With the second one the boost could only be used simultaneously with the other effect
My two favorite boosts are the Rangemaster and Super Hard On. The Red Rooster would be an ideal variant of the Rangemaster for your project since it is NPN and includes the very useful bass control. It’s also germanium so that is cute how it plays into the Ge theme
The Super Hard On is cleaner and more “transparent” although it does impart a nice sparkly coloration and gets really loud. I have built a lot of boosts and personally those are the two that I always come back to.
The LPB-1 from EHX is another classic.
If you want a really clean high headroom boost I recommend the madbean baconbits
