If you learn to fly on a nosewheel spamcan you should find it easy to handle - after all that is the purpose of the rules they were designed and certified against.
However moving onto aircraft with more performance will increase the challenges, scan through the old threads here about Cirrus, Mooney, Bonanza etc and you will find all sorts of horror stories from people who have not found them easy to handle.
The Vans (and a couple of others that look to have the same sort of arrangement - Europa, Sportcruiser etc) have long cantilevered noselegs hung off the firewall - compared with the certified designs I'm familar with this is a pretty flimsy arrangement - the nosewheel is 'free' to move considerably and that lattitude leads to shimmy and unpredictable behaviour. Worst if there is an overload it will often severely damage the firewall which makes for a very big repair.
On many of the spamcans, the noseleg sits within a tubular frame, often linked to the engine frame so the repair is to that frame only.
At the end of the day the Vans are essentially sport aircraft and designed to do that well, part of that equation is TW undercarriage - saving weight and drag.
