For me its speed, file size and accuracy of the Denoise. I'm pretty much sold on the degree of denoise in Adobe's AI via LR but the speed and file size is a no go for me. The stand alone Topaz Denoise running a batch of Sony A1 files is usually between 3-4 seconds per file. Adobe's version doesn't come close PLUS the resulting file size is approximately 225mb
No video card or computer I've ever tested is 3-4 seconds--what are you using? The absolute fastest I've ever seen is about 7-8 seconds per file, and that's with top of the line equipment (Mac Studio Ultra; even an Nvidia RTX 4080 or A6000 isn't that fast). That's half the speed of Lightroom but unless you're batching hundreds of files regularly, that's not a big deal.
As for file size, I assume you must be having Topaz DeNoise output low-bit sized TIFF or jpeg? Because when I have it create a DNG it's just as huge as the one LR creates, and the same size as a 16-bit TIFF file. In fact, the LR DNG is smaller than the the Topaz DNG or TIFF file. BTW, all Sony A1 files here, too.
I see from an earlier reply you posted that you are using an M1 Max MBP. I think your 3-4 seconds is an overly optimistic estimate vs. a measured number, unless you are using small raws or something different than I and others are using. As a refresher on performance numbers for performance testing I've done, here's a graph from this past February for a range of different Macs and PCs with various graphics cards using Sony A1 files:
The king of the hill in that batch is the M2 Max; the M1 Max was very consistent across several I tested (14" and 16" and an M1 Max Mac Studio). In the more thermally-constrained laptops it basically never does better than 8s per file on average when processing lossless compressed Sony A1 raw files.
An interesting note is that Topaz uses both the GPU and Apple Neural Engines; right now Adobe has stated that they aren't using the ANE due to a bug, but that using it will provide significant performance gains. My expectation is that we will see Adobe match or beat the Topaz times when this issue is addressed by Apple.
Unless you have a bone to pick with Adobe or have no use at all for Lightroom, I can't see much reason for using Topaz DeNoise any more. The file size issue is a non-issue, as Topaz produces the same large files unless you want to go straight to jpeg. The performance hit is minor now and will likely be completely gone when Apple fixes the bug. Finally, in all of the testing I have done, Adobe's denoise produces much fewer artifacts in files than Topaz does. In fact, that's the number one reason I was so willing to ditch Topaz. The new PhotoAI they are positioning to replace the current DeNoise/Sharpen/Gigapixel standalones is even worse in this regard, and on top of that is much slower.
