I have used Trimmer, Shaver and Double Edge Safety Razor (or DE razor).

Both Trimmer (below RM100) and Shaver (RM200+) are under Philips. DE you can explore this new shop called CHARMWISE.

Here's my comment and rank from the cleanest.

1) DE Razor: DE Razor definitely shaves the smoothest. There are lot of things to explore from the razor, to shaving soap, post-shaving cream etc. So the journey is more interesting than electric trimmer or shaver. DE might take longer time initially until you get used to it. Can do dry/wet.

Smoothness: 1st
Time taken: 2nd
Control: 2nd
2) Trimmer: If I need to shave fast, this is my go to. Although not as smooth as DE Razor, I think it's definitely smoother than shaver since shaver can miss a spot. I bought mine for a sub RM100 and only use this for dry shave without cream. Unlike DE razor where you definitely need shaving cream/soap to prevent from nicking, Trimmer can have better control in styling because your mustache/beard is not covered by soap/cream.

Smoothness: 2nd
Time taken: 1st
Control: 1st
3) Shaver: I bought 2 shavers - one the cheaper option and the other one more expensive, thinking it will do a better job than the cheaper one. BUT I WAS WRONG. Both are equally bad. It's hard to shave and sometimes you miss a spot so it takes more time to complete the shave. Due to it's design, it's impossible to get the smoothest using shaver. (Disclaimer: I am not sure how other brand of shaver would do)

Smoothness: 3rd
Time taken: 3rd
Control: 3rd
