Traditional shaving vs Philips OneBlade Pro

Hello.
I've tried a few products to hold long hair without residue and keep it manageable and so far I'm not satisfied with the results. Therefore, I have decided to record how the products that I have look like, and try the ones that you recommend, with the aim of finding the definitive product.
And what would this be? For me, it would be the one that gives volume to fine hair, that fixes, that offers a natural look, and that sets the hair back without the (so dreaded) typical line in the middle of jesus christ.
I hope we can help each other.
