So this has been talked about at length on this forum.
And while that shootout gives you an objective comparison to study, there is also the subjective and practical comparisons to be made.
Something I’ve learned this year, while really digging into using the OT by itself, is the newer Elektron Reverb algorithm is not at all missed when I am using the OT. It really does depend on how I’ve set up the Part for the tune I am making.
Of course YMMV, but again this is my own experience in practice, a plate reverb on a drum sound here, a dark reverb on a lead synth sample there, perhaps even some reverb that already existed on the sample I imported from Reaktor, and I don’t find myself needing that more dense modern Elektron reverb often at all.
When the tune does need a little more, a carefully crafted dark reverb on the master track FX2, with HPF and LPF dialed in meticulously almost always does the trick.
The variety of reverb algorithms, combined with the ability to use up to 8 of them at a time, each with different parameters and effecting different frequencies, modulated by dedicated LFO = complexity.
Even only 1/4 of this complexity more than makes up for that added bump of density the modern Elektron reverb has over the OT’s dark reverb.
