I am primarily a LrC/PS person, though I have On1 2020, most of the Topaz products and DxO Photolab plus the Nik Suite. I find myself working mostly in LrC as my DAM and PS with DxO PhotoLab as the place to go for Prime Noise reduction and the lens correction modules. Infrared shots I do in Nikon NX-D because it works well for proper white balance. I have just not taken to the On1 product, for reasons I cannot easily define. It seems OK but I am just more comfortable in Adobe world. The subscription fee does not bother me as it seems many of the other products are dipping theirtoes in that water too, or moving to annual "upgrades". Learn it and use what feels good to you and what suits your needs as most of the products are pretty good at what they do.
