Using teats from different brands on Pigeon wide neck

Recently, my girl has been fussy with the bottle and I had to buy a few brands to let her try, this is when I find out that the teats can be interchanged. To reduce wastage and reuse the bottles I have, should I just get the teats my baby likes instead of the bottle + teat? Example: pigeon PPSU bottle + MAM teats. I’m thinking of buying just the MAM teats and use it on pigeon bottles that I already have, instead of buying new sets of MAM bottles. Is there something I’m missing if I don’t use the full setup?
