I love jav, czechvr's, Nash's and John Strong's closeup missionary angles.
To me the biggest difference is that the SLR camera placement is closer to the face which makes it feel very intimate (and I love that).
I think they capture different closeup missionary positions:
Jav/Czechvr (and other studios): guy is hovering on top
- easy to appreciate the performer's assets
- fantastic body alignment
Nash/John strong (SLR): guy is literally on top, full body contact, and ready to go in for a kiss at any moment.
- easy to appreciate facial expressions
- legendary eye contact
I personally would love to see both angles and get rid of regular/far-away missionary shots (in my opinion).
I can't pick one angle because it depend on the mood (see assets jiggle or get lost in the performers eyes) 😅
