Elliptical vs Exercise Bike for getting leaner

I do some weightlifting but I also want to get leaner so I figure I should start doing more cardio. I like to run outside in the summer but when it's cold or rainy I think it's a good idea to be able to do some cardio indoors as well.

Just wondering what you guys think is more effective, the elliptical or the exercise bike? Or does it not really matter? I wasn't sure if one did more "work" than the other in the same time being spent on it.

Unfortunately I don't have a lot of money and there's definitely way less used equipment available on Kijiji/FB Marketplace compared to pre-pandemic. So I was thinking of going with either of these low cost options.
