I dont have a Strider Plus but was tossing up between that and the Phil & Ted Vibe. I ended up going with the Vibe on the main fact for me buying it was for the toddler seat (for next bubs).. but my 2 year old wont even fit in the strider plus main seat! She hangs out of it. She is tall but not overly. The Vibe main seat is huge.. my 4 year old fits in it with plenty of room and my 2 year old even in the toddler seat on the back. No way i could do that with the Strider Plus. Plus the wider wheels ended up turning me off aswell.
Best of luck with your choice.
