How can I say "I think the Eastern culture is much wiser than Western culture"? How can I say "I think the Eastern culture is much wiser than Western culture"?

I've tried "我想东文化比西文化很明智的", but Google is translating this as "I think the Eastern culture is very wise" (!!)

I'm in doubt if I should use a 是, or if I could drop the final 的. Like "我想东文化是比西文化很明智". If 的 is necessary, what's exactly its function in the sentence?
I think the Eastern culture is much wiser than Western culture

Translation：

"I think" can be translated as 我认为 我的想法是 我觉得 我的观点是 etc

“much wiser than” can be translated as 比XX更聪明 比XX更有智慧 比XX聪明的多 etc

In conclusion:

1、我认为东方文化比西方文化更高明。

2、我觉得东方文化比西方文化更有智慧。

3、我认为，相比西方文化，东方文化更有智慧。
