Recently, I've been preferring low g. I have two Kamaka HF3 tenors, and I was using the one with reentrant tuning almost all the time because I use it to play Hawaiian music in my two Hawaiian music classes. When one of my instructors said that he preferred low g (he plays an 8-string) for Hawaiian music, I began using my low g Kamaka tenor for Hawaiian music as well. I have a Mya-Moe tenor that's strung low g because I use it almost exclusively for non-Hawaiian music.
Having said all that, I believe that this is all a matter of personal preference and taste, and I wouldn't swap out the low g string of an ukulele if I was really enjoying the low g sound simply because a majority or plurality of people voting in a UU poll said they preferred reentrant tuning. If I were in your position, I'd definitely keep the Compass Rose low g, and if I wanted a reentrant tenor I'd use the KoAloha for that, because to my ear KoAloha tenors generally have a brighter sound than CR tenors, and I find that the brighter sound may be better suited to reentrant tuning. Or, if I really liked the way they both sounded as low g tenors, I'd just leave them that way because I think KoAlohas and Compass Roses sound different enough that your two tenors will sound different even with both of them strung for low g tuning.
