Which is better range indicators or no range indicators?

I've been playing support, and I have played without range indicators for a long time about 1 years and 6 months now, and I find it super hard to transition back, but I feel like I need to, because I don't know the range of the abilities sometimes, because it looks like Thresh hook hits and it doesn't, and when it doesn't look like it hits it does, and the same goes for Blitz pull, but it feels extremely slow when I go without range indicators everything has a delay now, and it's hard to play with for me, so I was wondering what is better.

Would you guys say without range indicators is better or with range indicators? (especially for supports with skill shots)
