Verdict
Two Pro-tier miners from the S19 generation. The S19 Pro debuted first with strong specs, and the S19j Pro refined the formula with a slightly different chip design.
Performance is very close. The S19j Pro has marginally better efficiency in most configurations, but the S19 Pro has a more established secondary market. For practical purposes, price-per-TH at purchase is the deciding factor.
