A couple of things to consider
Alexa and cranny have a 2:06.50 PR each however cranny set it this winter and efriamson set it last year. Cranny is not a slowpoke kick wise and even scalped hannah meier a 2:06/4:40 girl herself in the final 200 last year during some indoor champs.
However even if they are the same speed, alexa has the better kick/acceleration
FTR I would guess Alexa has 2:03 high 2:04 low speed with cranny having mid high 205 speed baxter hasnt run an 800 in a while but if she time trialed she could probably run sub 2:08.
If it comes down to a kick i'd have these 3 in that order as I listed them because they all have the best speed/endurance combinations of the group.
