Depends on your set up and where you;re fishing, Ihave both on different set ups depending on what it is I'm targetting
Braid is great for that direct feel where the rod tip shows every knock and touch on the lure so much so that you can feel the difference between weed on the hooks and fish plucking at the lure the downside is that if theres a lot of floaty type weed in the water then braid tends to pick it up
Mono is very stretchy whereas braid had just about zero stretch in it and in a diameter to diameter comparison braid wins out every time meaning you can up the strength of the line without sacrificing on the diameter meaning you fish finer and generally but not always , put more fish on the bank
Generally I would say that braid wins out but be careful that your rod rings are braid friendly or you could end up replacing them if they groove or your braid keeps catching or snapping
As for make, go for a manufacturer who produces round or as round as possible profile braid, a lot of it is oval or flat weave and not a lot of cop for luring as flat or oval braid creates a lot of water resistance and you tend to lose any advantage of braids lower claimed diameters
I use Power Pro a lot in different line strengths , made in the USA by Innovative Textiles who also make Tough Line XP, both good braids but then theres loads of different makers and brands some of which will appear on here later from other posters
