So my thoughts are that it depends what your purpose is.
As you say 1993 to 1995 that means you don't really need any of the ones that support System 6 and older, especially as they're often 68k code and don't benchmark PPCs with native code (some do, I'm not that bothered, I have other dislikes about them like where one popular solution seems to get "Math" and "CPU" backwards).
Really this leaves MacBench and Norton System Info.
My thoughts on this is that if you want a "Performance Quotient", MacBench is probably for you. It tries to give "real world" performance, with is a better indication of how a machine feels (especially if you work in publishing), but, my issue with that is it is opaque and carries any specific prejudices of the tests over. So if the scoring leans slightly towards some type of test that a specific machine does badly in, that machine will score badly even if it is good in your usecase (e.g. poor disk performance might taint the publishing graphics test, but your use case is games that run from RAM once loaded and depend on raw pixels to screen).
On the other hand, I always like Norton System Info because of the granularity - it tells you exactly what the individual test scores were, allowing you to work out how and where a machine scores well (as well as giving overall easy to read scores). This is generally what I use because when I'm comparing, I tend to be considering memory performance, or cast to integer, or trigonometric functions, or ability to translate an image vs draw a rounded rectangle or whatever. I like to understand the "why" and "what", not just a score. I realise this isn't what everyone is after. System Info also has an easy way of bulk exporting results which is super useful if you're doing an analysis of several machines and want to plot results or something.
As System Info doesn't immediately make it clear how to do things like drill down into individual tests, select which graphics card, or export results, I made a small writeup a while back. It might help you :

Oh, Norton System Info also has cat pictures. That also endears it to me.
