It depends on what you're looking for. The Pannonian east is a bit more boring if you're from more mountainous parts but it's great for farms and vineyards. Most of Styria and Lower Carniola (the north-eastern and south-eastern regions, respectively) are hilly which I reckon would be nice to wander around and explore, and those areas are parts of the vine-growing regions as well.
The more western parts of Lower Carniola as well as Inner Carniola (south) are a bit more on the wild side, they're hilly and quite forested. Because of the karst processes, farming had to adapt because in many places, rivers disappear underground and the landscape is filed with various karst elements. This is also the kingdom of the bears and the wolves so you have to be a bit more on guard if you go outside, as well as protect your animals if you're into that kind of farming.
The south-west of Slovenia is the warmest; this is mediterranean land. The coastline is obviously for someone who's into water activities and in general, these regions are known for vineyards and fruit, particularly the Vipava valley in the northern parts of the mediterranean patch that's known for the earliest fruit produce. There's also the Goriška Brda region (that tiny cut-off bit in the west on the map) that's just rolling hills as far as the eye can see.
Between the mediterranean regions and Ljubljana on one side and Ljubljana and the Pannonian regions on the other, there's a hilly expanse that's especially isolated in the west. Great hiking but a bit limited if you're living there. It's the alpine and the northern extents of the pre-alpine regions that I would say come out on top. The north-western parts centered around the Triglav national park, the Soča river valley, the upper Sava valley and the Bohinj region are the most popular among the kind of tourists that go for hiking and other outdoor activities. As for economical pursuits, much of the north is logging land and the basins are suitable for farming.
