В принципе если собрать посты sp193 с assemblergames, то появиться понимание какое-то, не обязательно это будет полностью адекватно положению дел, но думаю близко. Например от него:
I have to agree with l_Oliveira that the launch models feel to be superior in quality, compared to the newer consoles... but that's probably because it had a heavier construction. I found that it has its own share of problems, after losing two sets after many extensive programming sessions. :X

SCPH-10000 (Both releases of it), SCPH-15000 and the SCPH-18000 GH-003: KHS-400A laser (hard to find a 1:1 replacement!), poor CD/DVD drive tray design (l_Oliveira says that it's prone to getting stuck as dust accumulates), clock generator problems (apparently due to age?) and is difficult to maintain (parts are hard to come by) due to its considerable differences in design from the expansion bay models.
SCPH-18000 GH-008: Like a newer expansion-bay model (Has the newer EE), but has a PCMCIA slot instead. This may be more reliable than the earlier consoles, but it's not a launch unit.

Just don't mod the console if you really value it. Just get the HDD unit and use OPL to play games off it.

The Protokernel consoles (SCPH-10000 and SCPH-15000) have no problems running homebrew software. Some homebrew software don't work well on them because:
1. The kernel is older and has design faults that got rectified by Sony via patches, which get installed by newer Sony software. Homebrew software generally (the patches were only introduced in mid-2013) lack these patches. However, using the Sony system driver update or FMCB v1.9 will solve this problem.
2. Homebrew software seem to have to tendency to use board-specific files like the X-modules (e.g. rom0:XSIO2MAN) and/or rom0:LIBSD. These files are missing from the Protokernel ROM because they didn't exist back then. There is no fix for this, except for rewriting the software to not do this.

As for getting another PS2 for gaming, just get a newer expansion-bay set. I vote for the SCPH-39000 series (v7/v8) because it doesn't have the problems that the SCPH-50000 series has, and still has the i.Link port.

Slims are only good if you want a console with a reliable CD/DVD drive. They can't have a HDD unit connected to it.

If you go for a slim, go for the SCPH-75000, SCPH-77000 or SCPH-79000 series. The SCPH-70000 series has a lot of problems. The SCPH-90000 series seems to be crap (poor quality construction and the later units can't support FMCB.
Есть ещё шарящие форумчане, но думаю если даже они сами не сделали какое-то обобщение знаний удобно, с ссылками из профиля допустим, то здесь это точно не нужно.
