1098 is pretty clean, not a lot of esters or mineral or other Brit character. Can't say with S-04 if it's like that. I hear S 04 is "bready".
You can read Wyeast's or White Labs website info and they give pretty good descriptions of what the yeast character is like. If you want more Brit character, go more for one that says it has that rather than one that says it's "neutral, clean".
