Aisha way better than Flora
Not that it matters much in a fanservice wish-fulfilment story, but even for one of those Flora has virtually no personality outside of the ideal "shy innocent girl with housewife traits" that inexperienced, lonely young guys often adore. Even her character design is geared totally toward that. Cute, non-threatening, but so bland that it makes flour seem spicy. Nothing wrong with liking that, just not interesting as a character or as part of a story, especially something with a slice of life lean.
Aisha, on the other hand-- blunt, to-the-point, and just a bit crass compared to most Japanese characters. Works in the field, as her design shows, and has a younger sibling who helps her get dolled up when she needs to attend social events. Get you a girl who can do both. More straight-faced than most designs, but with enough sass and crudeness to make that charming. Is she even a possibility for romantic interaction in this series, aside from friendly bickering with Toakk? No. She still way more interesting than either ML or FL? Yeah.
