Just like GIMP compares to Photoshop. All the tools are there, maybe there is even more of them. However something feels "off", things sometimes freeze for no apparent reason. The less you know Lightroom the greater the chance that you will like RT
Fortunately for the alternatives that would describe Lightroom these days too, to the point that Adobe had to publicly acknowledge that performance isn’t good enough [1].

So, am I correct to understand that Adobe managed to botch LR so badly that PCs with vastly superior processing and IO to what I used back then struggle on basic tasks?
Woah.
(I had problem with their pricing though, so I switched to another (non-OSS) SW that is performing similarly for ~1/3 of the price)
