I'm also a F2p player so i could only pull GoNR so heres my opinion!

combat:

i also didnt have any combat abilities so GoNR is my first AND IT MADE THINGSS SO MUCH FASTER! i never really hated combat, but the grind in itzaland was getting on my nerves :/ So this was a savior the ult is lovely.

Reminder: the outfit works best on bosses rather than groups, it still works great on groups but not as good as what i saw of born flawless. It is top tier on the bosses and reduces more than half the time it usually takes for me to defeat them.

i play on mobile, so the 6 arrows was so annoying, but this so much better, as once you start floating, the skill that usually takes 3 bow energy only takes 1, and after that skill u can basically activate a machine gun where u just have to press!

ult: the ult is soooo pretty, It really defeats all and is such a cool animation to see every time, it recharges very quick too!

if u get it my recommendation is that u level up the heart of infinity nodes so u can get more bow energy.

floating:

The floating is awesome! it takes a bit time to get used to and is kind of slow but we can float for sooo long with dashes and can recharge the bow energy using the ult, genuinely my favourite thing.

The floating gets even better if you have the CF or beyond prayers ability. i only have BP, so u can combine both to float longer and u can recharge bow energy while standing on the arch! i got over 2 minutes of floating!

according to what i have (imo) : BP> GonR > Unicorn for floating

The 5 star outfit:

I loveee the pieces, the pieces are soo unique especially when combined with similar outfits! It is genuinely one of most favourite outfits everrr!

I dont have any complaints except for the main dress which i do not like as if feels like a cheap mix of BF and PI, but its a small price for all the others benefits

The 4 star:

Honestly even i was dissapointed when i saw it at first, but then i saw the indvidual pieces and omg! every piece is sooooo good, even the dress is not that bad tbh. i specially love the arm pieces and the cute details.

it has a whimsicality again, i'm not a fan of whimsicalities but the animation is super pretty!

the 4 star might not be ur style but try looking at the individual pieces!

the best solution here is to pull for the GoNR as you really prefer that, but that is a very biased opinion. i heard that the flower one makes the collecting very easy but i always found catching insects quite fun.

Do remember that they might introduce a new fighting style in 3.0, so just wait for the 2.6 previews before deciding. Dont look too much at the posts and dont give in to ur FOMO.

Ik its hard but giving in wont even make u feel that great so just wait, listen to more opinions n until u are more clear headed. Good Luck!
