check my list above
most of them have no ecchi except for few titles, like bento (only in 1 episode) and to love-ru

anyway, try this

fighting
code geass 1 & 2
katekyo hitman reborn

slice of life
kanamemo
bento
azumanga daioh

sport
cross game
giant killing

this season:-
ginga e kickoff (very funny and refreshing)
jormungand (interesting plot, except Koko is too cool)
natsuiro kiseki (like k-on, 4-girl slice of life show)
saint seiya omega (a young boy slowly becoming stronger to save his mom)
saki~ episode of side A (funny and cute and moe, about mahjong, middle school girls)
sankarea (a weird high-school boy with zombie fetish)
zetman (transforming, monster, hero of justice)

last season:-
nichijou (funniest anime ever, 24 episodes)

like k-on
kanamemo
A channel
nichijou
nichibros

movie or ova like summer wars
Toki wo Kakeru Shoujo

Steins;Gate - about science
puella magi madoka magica - about magical girl (only 12 episodes)
mawaru penguindrum - penguin
guilty crown - it's boring but maybe u like it
code geass s1 & s2 - it's like gundam but i think it's better
katekyo hitman reborn - a loser becomes stronger to become the 10th boss of the #1 mafia group Vongola
nurarihyon no mago s1 & s2 - this is good, about a half-yokai human. the similarity between this and hitman reborn is the hero is a loser while in their normal mode, but they become stronger when they get serious, to protect their friends n loves.

ixion saga dt is ecchi anime, like hentai etc
good anime is SAO, AW, CB, RB etc

Lovely Complex
Key The Animation
ef series (memories, melodies)
5cm per second
kimi ni todoke is good but it's not too deep
