I had a UR44 for a few years and was perfectly happy with it 'til the day I gave it away - I simply needed more channels and fancied trying out UAD stuff.
The onboard Yamaha Rev-X reverb was very useful for latency-free tracking reverb. The DSP powered guitar amp sims weren’t great - but they were good enough to hear what you’re going (feel wise) which translated well when re-amping the subsequent dry signal. The pre’s were good. Didn’t have any issues once I upgraded the firmware (doubt if that would be an issue these days). Depending on how many channels you actually need - the UR-RT2 Might be worth looking at - the same sound and DSP as the UR44 but with the switchable Neve transformer option for a mojo option - but it’s more expensive and only has one headphone jack.
Don’t overlook the Beringher UMD404HD, just as good sound as the UR44 - half the price but doesn’t have DSP (the latter is what drew me to the UR44)
