I signed up for a free trial of PhotoLab,
Frankly, I was underwhelmed by its performance compared to Adobe Lightroom. (Although, in fairness, I should point out that I only tested it with X-Trans raws.)
The X Trans support is still described as a beta option within the software, so best not to base any judgement on those files alone.
Did you try it with any older Bayer based files ? particularly anything with medium to high ISO with the DeepPrime noise reduction ?
This is where PL is a big step above LR. DeepPrime's ability to kill noise and reveal detail is really
so much better than LR's options it's worth the price alone (especially with the black Friday discount).
The lens corrections are a little more variable, some supported cameras get significantly better results than with LR, some aren't much different, anything unsupported can be better dealt with in LR and a custom lens profile.
I wouldn't use PL as my main imaging program, LR is still ahead on just about every other aspect of processing and image management. However I find running files through other convertors can often lead to different results that can sometimes work well in unexpected ways.
if I invoke Adobe's machine-learning Enhance feature, I usually get a more natural result
YMMV. I've yet to spend very much time with this option as I rarely need larger files, but my experience so far isn't great. I remain to be convinced it really adds anything worthwhile.
