。
It seems I'm not as excellent as you.
Literal
I [topic-は] you [extent-ほど] excellent [copula-じゃ] not [resemblance-ようです].
~ほど ('as much as') sets a benchmark: 'not to the extent of you.' ~ようです ('it seems, it appears') adds tentativeness — the speaker hedges rather than stating bluntly. 優秀 (ゆうしゅう, 'excellent, outstanding').
