I actually think it doesnt suit Vettel. Easy to drive doesnt mean suits every driver. It actually has exactly the characteristics he doesnt like, but we are unlikely to notice since Stroll isnt the highest bar to clear.
Just been looking at qualifying comparisons where "This is calculated by comparing the best times of a pair of team mates in the last part of each qualifying session where both set a time."

Average qualifying gap at Racing point:
2019 - 0.127s in Perez favour
2020 - 0.052s in Perez favour
If we're assuming that Stroll struggles to work out which way up to hold the steering wheel then I guess he'd need a stable, easy-to-drive car to get as close as he has to Perez in terms of outright pace.
