I would actually get accurate speakers whether I initially liked the sound or not. I think it would be important to train your ears to like the correct sound (= flat on-axis frequency response, but some degree of room gain and reverberation field effects are expected and allowed) and gradually adjust your own preference towards that.
If you just go with sound you already like or are used to, it's just accident of your personal history. It isn't, necessarily, the correct sound. One can learn to like a broad spectrum of different reproductions, so one might as well make music listening as easy to the brain as possible, and look for ways to make realistic sound reproduction the easiest. Outside of artificial sound sources like recordings and similar, there's natural sounds of room, people speaking, perhaps instruments playing; if these were reproduced by a speaker, one with anechoically flat on-axis response and smooth dispersion field would be the most likely one to reproduce these similarly. So an accurate speaker is really the most reasonable choice, and is always the first recommendation that should be made, and even if listener doesn't immediately like it, chances are this is just because they're used to the wrong reproduction and could become used to the proper frequency response.
However, there is another fly in this ointment, with the bass. Room is what makes the bass sound, and not really the speaker; the speaker obviously does create that initial pressure variation that feeds the resonant field of the room, but the resonance is much stronger and rapidly overwhelms the direct radiation of the speaker. Equalization can compensate for a lot, but doing it without any measurements is quite difficult, and for this I do recommend a measurement microphone and some time taken with tools like REW, to understand what the natural reverberation field looks like, given the particular speaker positioning and the listening seat position.
There are some recipes where e.g. listening seat is placed in specific coordinates such as exact center of the room, where all odd room modes will resonate the least, and the speakers are then placed in locations where they can energize second order modes as little as possible, and this sort of tricks allow minimizing the perception of the room's resonant field. There are other ways to do it, like multiple subwoofers that are strategically placed which can even out the bass. I personally have subwoofer and the main speakers all playing the bass together so that there are altogether 5 woofers in the room doing the bass rather than just one in subwoofer. Typically, the more sources there are, the more even the response becomes and the more it is possible to move around in the room with the bass still sounding similar.
