Is AI from campaign strong enough to make campaigns a real challenge (at least like it was in original)


Last week I finished all the campaigns available in original AoE. I already have the DE but only played it the first month from release, when AI in campaign was terrible and pathfinding even worse.

One month ago I started to play campaigns and some of them were difficult in some ways, the AI was more or less, hard to beat.

My question is if the AI from DE will be strong enough to make campaign enjoyable.

(I read AI is bad in scenarios, but I only want to play campaigns)

Thanks in advance and excuse my English
