Is the Shure SM7B worth it over a USB mic?

Specialist-subreddit consensus is that the SM7B sounds great but needs a clean preamp (often a Cloudlifter) and an XLR interface, pushing total cost well over $500. For pure USB convenience, the Shure MV7+ is repeatedly cited as the closest practical alternative, getting reviewers around 85% of the way for a fraction of the setup complexity.
