Best buggy board stroller attachment

Has anyone used a ride on attachment for their toddlers? I have a graco modes lx and am considering the lasco buggy board or guzzie and guss hitch, leaning towards the guzzie and guss due to weight limits. They both have very mixed reviews, but I can see the benefit since my son is 3 and still wants to pushed sometimes. I was going to get the graco sit and stand but got a great deal on the modes travel system, but still want a way to push them both. He’s 3 and already 41 lbs.
