In terms of 3D the general consensus is that DLP delivers best, but has been downgraded to "DLP Link" only (JVC uses 3D-RF glasses). Supposedly JVC isn't flicker-free (3D works at 96 kHz in contrast to DLP's 120 kHz), but my eyes are so slow that I neither notice flicker or DLP's rainbow effect.
4K eShift supposedly isn't that great with a JVC, but one of the recent Panasonic UHD players should improve the 4K performance.
With all you need to weigh up the Pros and Cons.
JVC - Pros: blacks and contrast, motion, lens memory
Cons: slow handshake, e-shift, expensive to buy and replace bulbs
Sony - Pros: Native 4K, motion and Reality Creation
Cons: low lumens, expensive to buy & bulbs, average HDR
DLP - Pros: cheap to buy, True 4K, motion
Cons: poor contrast, rainbow effect, no great HDR
Epson - Pros: cheapish & cheap bulbs, decent contrast, high lumens, handshake, lag, HDR, lens memory
Cons: e-shift, size, noise in high fan mode
Personally I don’t see e-shift as a negative on either the JVC or Epson but since the others are better I put it there.
