Better RegEx?

[former_member194669]

I want to find the "sbeed" from a string. I have written the following regex for that.

But I am in confusion which is better regex?

regex = '(?!sbeed$).*$'.

regex = '^$|^[^s].*|^s$|^s[^b].*|^sb$|^sb[^e].*|^sbe$|^sbe[^e].*|^sbee$|^sbee[^d].*|^sbeed.+'.

As the following RegEx processes little bit faster than the other while doing with large strings

regex = '(?!sbeed$).*$'.
