Decision time topic

Hi, I am about to buy Lg G3, but still can't decide should I buy 2gb/16gb or 3gb/32gb model? Is it worh that 50 euro to buy 3gb model... I looked all over the internet, somebody say that 2gb is enough and it works as 3gb and the only deference is the storage space. (16 gb-32gb) and some where I read that 2gb is even better than 3gb. What do you think? It's been a lot of time since this phone came out, so what do you think after playing with them? I am not a big gamer so I dont need a lot of RAM. I use my phone only for surfing on internet and sending some sms and around 10 minutes of talk time per day. Is 2gb enough for that? How does 2gb works with Lollipop? I have a lot of questions but I hope you can help me. :) :)

Thanks in advance,
Petar
