That may have improved in current models, but you never know.
My 2¢
I had the original with the smaller engine, and it was adequate power. Some people seem to think that they should be able to mulch anything at full speed or a mower sucks. In reality, all mowers need a place to put clippings, it ran great side discharge or 1/3 grass length mulching. I ran that first model for 4 hard years on multiple lawns and it never let me down. When i learned of the more powerful model i did sell my 1st gen and upgrade. I got a quick $600 out of it even with 4 years use under its belt. Does the newer model make a difference in power? Yes. It also empties the tiny gas tank faster than the old model. This is the only annoying thing about these mowers, the gas tank is pathetic. The self propel is also not up to the task of a steep yard. So if your not mowing up a lot of hills and you can mow your lawn on a reasonable schedule, either model will be powerful enough. The larger engine model is louder and wont bog down as fast. Give it thick and wet enough grass and you can eventually bog it down as well like anything else. Its not a mower for everyone, this is a mower for enthusiasts who can take good care of stuff. It has belts and things that might need more service than a one blade setup.
