Spike grenades are effective. Two basic tips with them.

1. Try to stick them just like plasmas, works about the same but much less range. Of course they usually only appear on indoor type maps (with half of Isolation being the exception).

2. Stick them horizontally on walls where you expect enemies to run past. Sticking them vertically on the ground requires your enemy to be standing on top of it for it to do damage.

Sticky grenades are amazing on Guardian, just wait behind a corner and watch as an enemy runs around the corner and you've got a sticky waiting for them.

In general if you are having trouble winning, work on your grenade skills. They have tons of uses. If you're running away from a losing fight, throw some 'nades to cover your trails. Smart opponents will stop and wait for them to blow before coming after you, giving you extra time to recover w/ teammates/get a new weapon / get your shields back. Stupid opponents walk into them giving you a kill. Grenades fair poorly in the middle of a gun fight, and are much more useful to soften up an opponent before killing them with an AR/BR/etc. Note the differences between them. Frags are great to throw around corners and have a wide splash radius but don't do a ton of damage. Plasma grenades can stick, have a smaller splash radius but can kill an opponent outright if they are close to the nade. Spike grenades are good for sticking, have the smallest "cone-like" splash radius, but when they contact they usually kill or severely wound.

Something I have to work on, but the BR was nerfed since H2, so you can't three-tap headshot kill people anymore. Instead it takes 4 headshot bursts, but it is easier to do body-body-body-head.
