Well, from a longevity point you did well with the basic Toro. The Super Recyclers are nice machines. One issue is that they are more sturdily built, but you did pretty well with what you had. You may find some operation differences that you like.
I have no real experience with the new Chinese Toro engine. I have however compared individual parts availability, and from that standpoint seem to be more component serviced than individual parts compared to a Honda or Briggs engine. I would look up the model number and compare if that is an issue for you. I see the same thing on other vendors that use the Chinese engines. IE many times a starter or carburetor is serviced as an assembly rather than getting the service part and repairing it.

I've had a toro personnel pace since 2000 it still runs great needs a new bagger decided in 2010 to get a new one and got one with an electric start so wife could mow had nothing but problems, key switch fell apart after war. would have cost 50-75 to replace I rigged some connectors to start it battery lasted about 18 months cover for battery kept coming loose and would fill battery comp. with clippings . power lever that engages personnel pace (plastic) broke very hard to replace had to spread handle to get piece out and new one in it took two strong guys. part was about $15 and 4hrs to replace . Seems like mower weighs twice as much it does start well with pull starter one or two pulls. also where plastic shield meets bagger (on top) wore holes in bag ( new bag over $ 100) needless to say I'm not as impressed as I was with my 2000 model and the electric start wasn't worth it.

I am not a fan of electric start on a mower. It is expensive and often does not spin the engine fast enough to start. Batteries don't last and are quite pricey. IMO, not worth the money.

I agree with Tom's take on the Chinese engines. External components such as starters and carburetors are not repairable, replace them. Internal parts such as pistons and rods are not available so it is a short block or complete engine. We are seeing this with Briggs too, all the Intek horizontal shaft engines are now built in China and unfortunately quality is suffering.
