Yes, the Skill Level Up M option ends up being the better choice for more strength gains, it's a relatively minor gain compared to the sheer benefit of both Helping Speed M and Ingredient Finder M at 25.
Both would be worth running, although you kinda only need one Gengar so better to invest in the one.
Ingredient slots are also the determining factor in whether or not you run a given ingredient specialist.
I didn't want to consider any Gengar that lacked Mushrooms on level 30 for example, as it's one of the best gatherers of mushrooms even if fiery herbs are technically better for raw strength. Ingredient diversity is too important to being able to consistently make the better dishes.
This is a pretty lovely Gastly (now a level 30 Gengar) I befriended recently, and she's been amazing having gathered 70+ mushrooms in a few days when I was short on ingredients.
BFS at 50 is an interesting change, it does result in a slight reduction in ingredients gathered but ultimately greatly improves the strength gains.
