Reviewing major differences between Softube Model 80 and uhe Repro5. I mainly spotted on featurewise factors that can be objectively verifiable.
You can download these comparison presets to check sounds by yourself: https://plugmon.jp/model23/

Notes:
The question "which is closer to a hardware?" is not on the table here.
Sound quality is more or less transformed throughout recording, exporting and uploading.
I'm a heavy user of Softube Model 72, American Class A, Tape, Dirty Tape and uhe Hive and Diva. Though I tried to be mindful of keeping it as fair as possible, I still might have played favorite with uhe because I have worked with the guys a couple of times before. I highly recommend that you check the points shown in the video by yourself and see how it feels like.

After posting this, my friend taught me that you can actually kill the click noise in Repro5 using modulation. See the video below for details:
