I can't see that. Maybe in very specific cases - very fast circuits with minimal braking (like the old Osterreichring) on race pace - but on most they ought to be much quicker than FF with more downforce and much more power (around 335hp equivalent, though with much more torque) though significantly heavier too of course. Certainly in qualifying where they don't have to regen and have more power (and 140% more power in the upcoming Gen3 car (around 470hp equivalent)).
The top speed of a FE car isn't 120mph as you said earlier. That's probably the sort of speed they top out at on most of their short city track straights, but the cars themselves are apparently capable of 174mph.
Like I said earlier, comparisons are difficult, but all in all they were around the space speed as what an F3 car would be around Monaco, which as far as I know is the only track we can use as a comparison.
