/app/default/test points to executing your test() inside the controller named default.py args and vars are, in respect - args : /app/default/test/*1/2/3* - vars : /app/default/test?*foo=bar&foo=bar2&hello=world*
To sum up, args are fine if you want cleaner urls, but you can't put whatever you want on them (imagine something like /app/default/test/*รนร +:\*/ , not a "smart" way to pass garbles on the url, but, e.g., something like /app/default/test/*1/on* where *1 *is the "bulb" number and *on* is the "action" you want to do seems fine). "Vars" on the other hand allow more flexibility, "garbled" parameters are allowed...maybe the nicest "feature" is that if you need a single variable holding multiple values "vars" parses them automatically (e.g. "turn on bulb 1 and bulb 2" can be done with /app/default/test?* bulb=1&bulb=2&action=on*) . Urls are not "clean" as with "args" but the functionality is the same. Bottomline, use what you feel appropriate, either one would do just fine.
