Most natives take real values as their arguments, and return reals.
Locations have the extra overhead of needing to be created and destroyed.
When using real x/y values instead of locations you don't have the extra overhead of GetX/Y and MoveLocation; this leads to both easier to read and more efficient code.

There are times when locations are needed; such as getting terrain height etc. So it's not "don't use locations", but rather only use them where they are appropriate.

abriko	It's different ! :p Location is x AND y. You can't apply mathematic and dynamic transformation with the location or that is always proportional.

Tide-Arc Ephemera	Locations are easier to let leak. Coords don't leak at all. Also, things which require locations often interrupt unit orders, making them a bit odd when making unit abilities.

zen87	locations are objects, they eats ram memory by leaking x and y are reals, they don't leaks

ADOLF	so... use location when: you need to find coordinates where was cast spell (GetSpellTargetLoc()) or you need Z coordinate of terrain JASS: globals location l_temp=Location(0., 0.) endglobals //... call MoveLocation(l_temp, x, y) set z=GetLocationZ(l_temp) in the rest it is faster and more convenient than coordinate

Dark_Runner	Hmm

Rising_Dusk	I only use locations under the case where I need a Z-coordinate, since that's impossible with just X/Y. Otherwise, I avoid locations like the plague; senseless handle declarations are silly.

Themerion	Using X/Y is a little bit (a very tiny bit) faster than using Locations. Also, Locations create small (very small) memory leaks if they are not removed with: call RemoveLocation(myLocationVariable) If you are going to post something at wc3campaigns (a system, a spell, etc), then you should probably use the X/Y. Otherwise, it doesn't really matter much.
