i've done a lot of glass etching. i have used the armor etch cream, i have used my 30 watt laser,as well as hand carved techniques. the etching cream is very faint imho. the laser aint much better. the granddaddy of em all is sandblasted effects on glass. followed perhaps with a bit of rotary diamond work on details. the sandblast technique is visibly superior as it shows a bit of depth. actually a lot of depth if you know what you're doing.
