It's always interesting to me to observe how people's opinions on here can differ so greatly on things. I've noticed that some people want to get their primary stat to 20 ASAP while others are content to keep it at 16 for a really long time. I typically like to max my primary stat early on, and, ignoring the vhuman feat, won't even consider a feat until my main stat is at least an 18. I'd say that when using point buy or standard array, I've taken the stat bump 100% of the time at level 4, and it's probably close to 50/50 stat bump to feat at level 8.
I've known players that never choose feat and prefer to bump their stats 100% of the time, and then I knew one guy who was a high level Fighter and he took a feat every time and kept a 16 for his entire career. His character was effective still, but he did miss a lot with his attacks. Maybe not a lot, but noticeably more than my character did with a 20 in my attack stat.
So I already know that I value having a 20 in my main stat more than the average player, but I'd like to see how everybody else feels about it.
