The reason I'd recommend the Glove80 is because a keywell is just so much nicer to type on, especially if you want to actually be able to use the number row without straining your fingers. Their thumb cluster is also the most sane one that I've come across, and the absolute though put into the design is astounding and commendable [2]. The article is definitely worth a read.
I recommend the Voyager especially if you are a believer in 1DFH (1-distance-from-home)[3]. It has very few keys so you'll have to learn about layers [4] and/or home-row mods[5] or my favorite callum-style mods [6].

Looking at custom keyboards, the Dactyl is probably quite good.
[0] Even if it’s a huge step above normal keyboards.
The thumb layout is designed for very large hands and way too many keys in difficult to reach positions.
Fact is, there's no one keyboard that's ideal for everyone.
