How do Microsoft Rewards- (Bing Rewards) Members Decide whether to ''Donate'' or to Try to ''Win''?

You know Microsoft Rewards (maybe Bing Rewards is a more-popular name), where members earn points for doing searches, buying services, and other things ... especially 'clicking a selection of links they give you every day.' When you want to redeem the points you've earned, they give you three categories of prizes to buy: Shop, Donate, or Win. https://rewards.microsoft.com/redeem/ 'Shopping' usually requires "spending money online"; and I don't spend money online, so that's a "no-go" for me. In 'Donate,' Microsoft offers a collection of charities you can 'donate your points to' (i.e. instructing Microsoft whom to donate money-to in exchange for amounts of your points). In 'Win,' Microsoft offers a collection of prizes (video-game systems and other equipment) you can exchange your points for more-&-more chances to win. I've been a member for I-don't-know-how-long (since 2018, I think); and I've donated plenty of points (earning a few badges for it), but I don't think I've ever won any of the sweepstakes ... But maybe it's because I've spent too many points on donations ... should I keep donating, or should I switch to 'entering sweepstakes' until I win something good?
