In most solvent programs, its not a "use or lose"... just fly them once between now and the expiration date, and you keep the miles for another ~18 months.
MP and OneWorld are two of the stronger global alliances - betting your mileage bank on both is a reasonable diversification strategy.
On the OP, I believe that UA treats its MP elites better, particularly above the 50K level (MP 1P, CO ??). Below that then its arguably a crapshoot, although E+ at the 2P (25K) level is a bonus with UA metal.
