Wondering if anyone can confirm if the calipers are the same and what the exact weight differences are? Been trying to search online but the figures seem different depending on where I go.

The rear caliper is setup as a flat-mount configuration, if that makes any difference. Thanks.

The most significant difference is the price.

r2-bike.com will list the weights.

For compatibility, shimano have a document explaining what is supported, but most other combos also work. Normally, a person using XTR is not going to mix with SLX components ...

Cam over on NSMB recently did a really interesting article on xtr vs deore groupsets. It kinda puts things into perspective. Not exactly what you are asking, but an honest good read worth the 5 minutes.
