For me, the answer is to learn to shave with both and then choose the best head and handle combination that works for you.
Whilst I prefer longer handles, I’ve found that some short handles (such as an ATT Atlas) generally work well for me, whilst other short handles (Timeless and Blackbird for example) really didn’t work that well at all.
Sometimes the material the handle is made from can be a deciding factor. I find that an aluminium Razorock Halo handle works for me, whilst I struggle with the stainless steel and titanium versions of the same handle.
It’s all about getting the right balance in order to a get the best combination that suits you. It really is a something of a personal thing and is another case of YMMV.
