I hate the smell of neroli. What is the best cologne to cover it properly?
Many colognes will cover Neroli effectively.
Ones I use are:
Daytime/Work:
CK Eternity - Light clean/fresh/classy slightly citrussy cover but I’d say it sits well with Neroli and pushes it back in the mix but not entirely it also won’t cover all mones effectively, notably none mixes - TUTH and NPA (above 0.8/5ml) in particular
Azarro Chrome - distinctive, fresh woody/leathery scent. Effective even for IJ and NPA up to 1.5/5ml
Chanel Blue - As above. A bit sweeter and softer (powdery even?) than Chrome but still a good daytime scent.
Night time/clubbing:
Blue Sugar -Very effective/economic quality cover for everything I’ve used so far but may struggle with IJ. Also usable in daytime at one spray.
Armani Code, standard (Black?) version, “Sport” Code is much lighter - Covered everything I’ve used very effectively, incl NPA up to 2.3/5ml and multiple sprays IJ. Also a sexually attractive scent in its own right and combines with Akuto superbly.
Cool Water - An excellent cover and popular scent but its at my limits for irritation, so not used it as much as I’d like.
Chanel Antaeus - Strongest scent I’ve used, distinctive (quite floral) and very different from the sorts of scent that guys tend to wear in my neck of the woods - which is a plus in itself. 
Also used something called “Terrain” which has all the robustly powerful, earthy type scents that are currently very fashionable and claimed to have phero-like qualities - Personally I think of it as “Instant Gardener.” Might go down well with eco-lovin gals!
And there are several threads in the Perfume Forum you might want to look at as well - other guys have listed their fave covers.
mobo is right about armani code.the smell alone is very sexual to alot of ladies and it cover any mones really well
Wow dude never thought anyody could dislike Neroli. Tastes actually ARE different 
I’m ordering Neroli in regular cologne strength next cause it smells so damn good.
Hope you find a cologne you like man!
