Brilliant Pebble Wireless?

Hey! I just want to be prepared for when I'm no longer a student and will need to invest in an audible alti. Brilliant Pebble's pretty cheap compared to other altis on the market. Are there any drawbacks on the quality or reliability? What are the reasons why someone would opt for a different audible (like an optima 2 or a solo 2) rather than the brilliant pebble wireless?

(P.S. Will work my way up to a VOG within a year or two when I can afford it! 😅)
