www.minecraftforum.net/topic/249637-145-optifine-hd-d2-fps-boost-hd-textures-aa-af-and-much-more/
I think that the Standard is good. I use the standard Optifine.
When you has make it,you go in the Magic Launcher and go into the data Setup(Its over options in the Launcher).
You create a new configuration. The name it is doesn't metter. When you has do it, you can click on ,,Add'' and add a mod. A Texture Pack can you use when you makle it on the Minecraft Texture Pack order and you can use it when you change it bei ,,Texturepacks ''.
But with Optifine can you change the Texture Pack ingame!!!!! And you can make better grass and you has got better glass!
Thanks and i hope that i have help you!
