Is St. Ursula in Wilrijk a good school?

Can someone tell me something about St. Ursula in Wilrijk? My son is now in the first year of preschool at the Parkschool (De Vlinderboom) in Borgerhout, where I’m happy. We’re moving to Wilrijk at the end of this year, and I’ve already enrolled my daughter (20 months old) in the same school as her brother, but I’ve also registered in Wilrijk. Now she could also start at St. Ursula, but that’s a Catholic school with uniforms from primary school onwards... Not really my thing since I’m really non-denominational. On the other hand, I’d have to drive 6 km to keep the current school. Can someone tell me if St. Ursula is good, very Catholic, or is it not that bad?
