is 45 better than 90 when repairing a leak

I need to repair a double leak in my lines. I am debating between using 45's or 90's
It seems that a 45 will let the water flow better. However, the reason I need to do this repair is that the builder messed up the original lines I think and then had to cross them over and used flex pipe and 45's. Now the 45's are leaking. I am not sure if it is the 45's or because of the flex pipe. I am pretty sure it is because the flex pipe.

So when i do the repair I will do a couple of U's and was wondering if a 45 will seat and hold as solid as a 90

I would cut out all the glued fittings on both pipes in the photo and replace with pex pipe (burial type) and pex to pvc adapters. There would be no 45s or 90s.

The failure has nothing to do with the fittings being 45 or 90.

45 have a better flow rate than using 90 fittings. If you've got the space two 45's will flow a bit better than one 90.

I did not mention that my PVC pipe in the ground is 2" I think that might be too big a drop to go from 2" pvc to a small pex. I don't know how big pex / pex fittings get but I have never seen a 2"

I like the idea of the 45, it does seem that flow would be better and in some research I have read it seems it isnt much better but is at least 5% better.

45's would also keep the repaired pipe closer to the lower pipe.... less of a hump.

Hey guys,
I went with 90's since there is not really any flex in the pipes and I wanted to get them as fully seated as I could.I am thinking about putting some plumbers putty on each of the joints. It may be overkill but I don't want to have to ever dig this hole out again. Is there any bad side to putting plumbers putty everywhere?

The top image is my repair the bottom is what it was like before.

The glue is all you need.
