I originally ONLY chose Whistler (1098) because of the remote head. My new toyota highlander was not radio friendly for fitting the DIN-sized BCT15x that I love and adore and could make sing anywhere in California, and I didn't realize the Uniden remote head was discontinued long ago. I wasn't sure about buying a scanner from a CB company, but everyone here seemed to love this dark horse, and my hand was forced with remote head, so I took the plunge.
Now, compared to the 15x, I've come to like the additional space (200 scanlists vs 100 systems, and eventually v-scanners as I re-think things), and ability to toggle a channel priority off/on. I only have 1 boring Moto T2 system nearby so I don't get to play much in other trunking unless I travel, and digital is pretty minimal still up here in Northern CA. So can't sing praise of Phase2/simulcast/DMR like others can. I have a love/hate relationship with RadioReference but enjoy the ability to save time by loading up some data from the library and fine-tuning afterwards, vs. hand-entering it all.
What I don't like still (or "why I miss my 15x"), I hate the programming software still (but it's a love/hate relationship, I've learned to cope), the physical buttons are very small and cheap-feeling compared to the 15x, requiring a precise well-defined tip of finger press, vs a quick not-precise push of the finger for the 15x, with crappy button backlight. This is huge for me while mobile, easy drive-by-braille on the 15x but have to take eyes off road to operate the 1098, and any bump in the road negates any precise finger press.
I also still don't fully trust my RX on the 1098, I feel I'm losing conventional reception during a priority channel check or something, where it stops on a decent conversation that I know will last a bit, then the priority check happens (maybe 5 channels at 2.5sec interval) and the scanner doesn't return to the conversation that I know was at hand. I'm almost tempted to throw the 15x on the pax seat with a magmount and see if true or I'm just going crazy.
