Do you like how they sound, so far? Get them, explore them. They’re great modules, and both of them also reward exploration beyond the “cliche” of Rings into Clouds.
There’s no way to do this right or wrong, but avoiding modules you like the sound of because they’re widely used seems like it might not be the best way to direct your explorations.
I started with a pair of Mother-32s and got a fair bit out of them, then added Maths, a Disting, and Ornament and Crime. I think modules like Disting and Ornament and Crime are especially good early on because they are versatile tools that let you explore a lot of options.
If I were starting again today from the beginning, I would probably get an O-Coast, Maths, and a Pressure Points, and put the latter two in a 4ms Pod or a Palette case. Fairly affordable, and you can get a lot out of that. Actually, that and a MIDI keyboard and some reverb sounds like a really good weekend…
