Yes, Formulaire is the best choice if that's the only functionality you need...form, send results to an e-mail address, that's all. Formulaire does that very well, right out of the box.
To do it in Formulize, you have to create your form, then you have to set up the notification condition you want on the form (ie: when a new entry is made, send a message to Webmasters, or whatever), and then you also need to make a custom message template that will contain whatever information you want from the form. So lots more steps. Lots more control, but if you just want a straight forward message, use Formulaire.
XOOPS trivia: Formulize was forked from Formulaire 2.8 five years ago.
