Honestly, I browsed Smogon (though I preferred Selebii's Pokémon of the Week), but I almost never implemented them. For one thing, it's hard to get a good feel for an entire battle layout/strategy from the breakdowns. But, for another, it's of extremely limited use in standard gameplay. I'd take Flamethrower over Fire Blast any day, not only for the accuracy, but for the PP. So many of those setups wouldn't last you through any of the caves, or are so min/maxed focused that I think they cease to be fun.
I use their advice for overall utility, which Pokémon are good at walling and support, or what the best cross coverage moves are. But otherwise, I tend to focus on creating the best anti-AI team I can. Which, admittedly, isn't that hard, but it's the way I like to play, and it's a lot more fun, especially when you can start free-forming things and creating unique setups.
I love creating my own Pokémon. I was one of the few people to run a full Special Lucario, or use an all-crit Absol. Everyone recommends Sucker Punch, but Night Slash is so much more fun, and Absol gets Psycho Cut and Slash too (sometimes Stone Edge, but I don't like the 80% accuracy), and with a crit-booster held item and either Baton Passing it Focus Energy or using a Dire Hit, that little guy got crits like crazy. I love analyzing all the moves possible for a Pokémon to learn, figuring out which ones I'd use and how to team them up to have a one-Pokémon team wrecker (against the AI, because I only play single player). And the tournament suggestions are rarely usable for that.
