It really isn't that hard to max them out. I'm at July 31st and I already have Faith maxed, Councilor as far as I can go until September, Temperance at 8, Sun at 7, and Justice at 4. Just make sure you have a persona of that confidant with you and you'll breeze through it easily. I did all that without sacrificing social stats(mine are all at 4 now) and Ann and Ryuji are at rank 8 on theit confidants, and Makoto and Yusuke are at rank 4. Sojiro is the only confidant I haven't put a lot of time into, but I won't need him until a little later anyway.
I'm tryna figure out am I gonna fukk Makoto, Haru, Futaba, Hifumi, Kasumi, Ohya, or Kawakami this time. I did Ann in vanilla so I don't want to retread it again... leaning towards Makoto or Kasumi though. Heard Makoto has the best romance story out of all of them.
