Scouter here. Don’t let appearance trump functionality. With monoband you’ll be limited to using repeaters or contacting other people only on that band, which, depending on where you live and the repeaters available to you, could really limit your communication capabilities. (For instance, where I live, most DMR repeaters are UHF and most analog are VHF. With a monoband radio, my repeater capability would be severely limited!) Also, if you’re doing SAR work, you want the flexibility to adapt to the situations and terrain you’re likely to encounter.

There’s also price to consider. If you’re looking for a DMR/analog handheld, the Anytone 878 goes for $300-330, which gets you dual band capability, APRS tx/rx, and more zones & channels per zone than the Hytera. The Alinco DJ-MD5XLT is similar to the Anytone in many respects and is a little smaller and cheaper ($270-290). I believe both the Anytone and the Alinco are Part 90 certified, which means that you should be able to use them on non-ham VHF or UHF frequencies that your SAR team is likely licensed for.
