I disagree. I think English does have some inherent advantages. I can't say it's the "best", but it's certainly better than some alternatives.
There are some specific things that make it "easier" to learn: Latin alphabet with no accents, no genders, small conjugation tables, few tenses, very "relaxed" grammar. In this way English is a subset of rules already understood by other speakers.
What also needs to be mentioned, though, is its expressiveness. There are many objectively "easier" languages than English. For example: Afrikaans has a very simple grammar, being essentially a "stripped" Dutch; Spanish has a much smaller vocabulary. But all humans talk about the same things one way or another. A language being "simpler" means there must be other ways to communicate those more complex things. It's often done using very specific and nuanced rules based on context and culture.
English, on the other hand, can be mostly learnt in a book. There's not much culture to learn as English culture has already been exported widely around the world. You're much less likely to end up in a situation where you have no idea at all how to express yourself using the rules you've learnt.
There are definitely accents in English. They are just not written down which makes written English very confusing as nothing written has proper prononciation rules.
