I, when I started trying learning CFOP, tried to learn the Algs,I wasn't too good at that so I learned intuitive F2L, then i did better times, and even i could create some 'bad algs', but for me, that was the way to solve some awkward cases... the point is, that when i got better, i realize that the only thing that really ruined my times, was F2L(my cross + 4 F2L last most of the times, more than 20 seconds), I mean, algs with no triggers, mirror algs that didn't fit my style at cubing well (i have a great Right hand, at executing, and a great Left hand, holding the cube but not vice versa), so i'm now learning the algs, and most of them uses triggers and are fast, my final thought is that is good to start with intuitive F2L for 2 reasons: 1) you develop better your look ahead, and your understanding of the cube 2) allow you to progress faster and that means, to reach sooner the point where you can make a difference with the knowledge of an alg, because if you start with the algs, and you have a bad look ahead, ¿what is the point of to know a good alg which save time if you lost that time rotating the cube for to look for the other F2L case? and even more¿ will you practice more if you see for a long time no progress at all? , psychology plays a role in here...
