Little Informal Comparison... 1) Metashape [MS], 2) CaptureReality [CR] and 3) MapsMadeEasy [MME].
Exact same file set of images... 302 from a X4S I2 @ f11 (X4S is same camera on P4P, Mech Shutter up to 1/2000/s )
I own neither of the 2 programs, both are local installed. Exploring CaptureReality, purchased 30,000 PPI credits, and understood that provided a 'Fully' Functional version, but I've noticed the 2D Ortho have a "watermark" plastered all over, and the 3D model does not. Still exploring. The MetaShape, using a 30 day Full Functional Eval (each system can get a 30 day)
Things I've noticed: Detail of 2D is currently MS, but CR may have much more to tap once I learn more. It hints of much greater detail. The Color and EV & Contrast of CR is much better. The shadows, and overall brightness provide greater detail.
The blend of multiple photos and removing artifacts, moving objects (cars & people) are cleanly removed in CR, and removed Partially in MS.
Hole Filing is better in MS, but that is most likely me not knowing CR too.
On the 3D models... Both are auto mode, no tweaks or adjustments.
This is one area I felt was much stronger on CR, the NADIR shots normally give poor 3D results for any 1) Overhang, 2) Long non-color changing verticals, 3) narrow objects (ladders, cranes arms, etc), 4) vertical holes.
The lack of detail under overhangs is common in all the ones I've experimented with so far... but the CR is a few notches up. It's not useable detail, but it makes the biggest attempt to provide detail.
Example: 3D, look at the 2nd Floor foundation and the 1st Floor underneath. MS is a gapping unfilled hole. CR captures the first 2-4 feet under the overhang.
TIME to process -
On a Mac Pro 5,1 Dual Xeon 3.46 Mhz 6 Core / 24 thread processing, 128 GB RAM, GPU 1080Ti 12GB, Windows 10 v2004.
MME returns a completed message on avg for 280-350 photos in about 5-7 hrs.
MS 300 photo avg, takes about 5-6 hrs to process. (this project 5 hrs)
CR 300 photo avg, takes about 1-3 hrs to process. (this project 1 hr)

Didn't grab a close up of CR, but examine the detail of MS close up on 2D...
This is the same 2D Ortho as the MS 2D at the top this stack of pics.
Locate the Crane shadow and stump on both wide & close-up.
