Short answer: both are discontinued, and they are rated the same for sound quality (#10 and #8 of 179 medium speakers). Either one is only an option used, so choose on condition and price. If you want one new, the Minirig 4 replaces the Minirig 3 and is rated 4.3/5 at $229.95.
Buy the B&O Beosound A1 if you find one in good condition and want a weatherproof, travel-friendly speaker with better everyday connectivity.
Buy the Minirig 3 only if modular wired or wireless expansion is specifically your goal and you accept its older charging system and ownership risks.
Water resistance is not close: the B&O Beosound A1 is rated at IP67 (brief submersion), well ahead of the Minirig 3 at Splash resistant (splashing).
