Idk if the showroom guys have control over that because I asked for Apollo and I got MRF. The sales guy told me the bikes get allocated at random.
But coming to the tyre itself I would say the MRFs are good only. Never felt the lack of grip except one time when my tyre was in slushy mud. Appearance wise also the MRF's look a little wider compared to the Apollo's since the tyre profile is more curved in the latter if that matters to you.
