I wouldn't recommend them at all, really. The use of 3D Custom Girl assets should immediately make clear the sort of quality we're talking about here. Still, the fact they typically occupy the netorare SRPG niche always made them interesting to me.
They're basically Fire Emblem games where you can select a difficulty between: 'You cannot lose', 'Normal' and 'Literally Impossible'. The point being that whenever one of your heroines is defeated, she'll be captured and fucked afterwards; after a few times of that and a few different scenes, she'll be corrupted fully and will betray you in the final battle, literally joining the enemy's side as a unit you need to fight (essentially making victory impossible, which is fun on a meta level). They actually have some interesting gimmicks that play on the FE formula sometimes; stuff like villages which you'd expect to visit for items actually spawning enemy reinforcements, same turn reinforcements in general and other traps to make it difficult to keep your heroines safe.
Still, they are essentially shovelware. The scenes aren't great and the writing is poor, so I definitely wouldn't actually recommend them to anyone, it's just that I personally don't mind wasting time on bad games that have nice scenarios or interesting gimmicks. RJ343148 at least doesn't use 3DCG assets, and had some nice corruption, so if you really want I'd pick that one; none of them are worth actually spending money on though.
Besides, as far as netorare SRPGs go, you can forget about the above because the game I've been wishing for is almost here:

Orphanage is a netorare SRPG with great art, a large cast, plentiful scenes, even custom sprite work (including animated special attacks!) and enemy gimmicks! All of it done by one guy working for years. Already a next year release I'm massively hyped for and a day one buy for sure.
