What Lau said. I think going for a 20 at level 1 is just sacrificing too much. I've tried going with a Strength of 16 for a frontliner and it just doesn't cut it, but 20 is overkill as well. 18 is the sweet spot. A 20 in a stat also leads to way lopsided builds that just sacrifice too much, I think.
An example: a guy in my lodge made a Kineticist with a 20 in both Dex and Con, and the rest is pretty much 7, except for Wis, which is an 8. He has no real skillpoints and can barely contribute outside of combat, but he's a passive player, so he's okay with it. But it also effectively removes one person from doing the challenges. Everything that's not Dexterity based, he sucks at. Investigative scenarios, survival scenarios, social scenarios, he's pretty much dead weight. In a balanced party, that can be overcome, but there will be a time where the party's wishing they had at least a somewhat capable person on hands.
Second example, from myself: I made a Cleric that's incredibly MAD. I had to dump Dex and INT, because I pretty much needed all other stats. As I dumped INT, I realised that it didn't matter whether I had 9 INT or 7, as I got 1 skill point per level either way. So I dumped it to 7, and chose Nagaji as its race, dumping it even lower to 5. My first PFS character was also a Cleric with dumped INT, and I spread his skill points around, thinking that I'd be good at everything, but around level 6 I realised I'm actually crap at everything, so I experimented further with my Nagaji Cleric. I put every single skill point I had in Diplomacy (he has a Cha of 16). My reasoning being, I can spread it around, doing maybe 50/50 in Diplo and say, Sense Motive, but that means I'm watering down what I'm good at. So my derpy little Nagaji is the dumbest, nicest guy you'll ever meet. I've missed several faction-specific boons because they called for skills I didn't have, but I'm okay with that, because that's the risk I'm taking. But every time I play him, I feel a little bit guilty when we're doing skillchecks, as I suck at 95% of all skills. I'm effectively dead weight at anything that isn't Diplomacy-related. Again, so far, that hasn't been an issue, but I fear the day I'm involved in a chase scene and I need to cross a bridge with my Dex of 8 and an armor check penalty of 5...
