The first 2 seasons of ENT are better than the first 2 seasons of DS9, VOY and especially TNG. My god he first 2 seasons of TNG were atrocious.
I'll take the first two seasons of DS9 and VOY over ENT.
Also I'll excuse TNG's first two seasons since it was the first modern Trek series. They were still learning how to do Trek without Kirk and Spock. Even as bad as the first two seasons were, we got a few classic episodes like 11001001, Datalore, Conspiracy, Elementary Dear Data, The Measure of a Man, and Q Who.
I can't remember anything about the first two seasons of Enterprise except for the horrible A Night in Sickbay episode and how bored I was through the first two years.
I like A Night in Sickbay personally.
That's a few more than I would've put for TNG.
Personally the way I sort of rank the series' are 1st and 2nd seasons of TNG, DS9 and VOY are nothing special but may have a few very good episodes in there somewhere (though for TNG that's only like 2). 1st and 2nd seasons of ENT and 3rd season of TNG, DS9 and VOY are hit and miss, some great episodes, some pretty bad episodes. 3rd and 4th seasons of ENT, 4th season onwards of TNG, DS9 and VOY is when they really hit their stride. I just don't like TOS.
But to each their own, we're quite far off topic.
