Realme 3 Pro 4GB 64GB/ 6GB 128GB

I’m getting confused to get which varient of realme 3 pro, Like 6Gb/128gb cost ₹3000 extra from base varient.
So is it worth to spend more to get top varient.
Basically I’m a light user, don’t play games like pubg, 64 Gb storage is sufficient for me and it has also dedicated sd card slot. So 6b ram makes noticable difference in performance when it compares to 4gb ram.
Please Suggest?
And my budget is also 14k, but should i spent more to get top model as per my needs or not?🙏
