I guess it all comes to the simple question: how to play a piece the best?
V-Accordion gives me more tools to fulfill this goal, more than an acoustic accordion. It doesnt need to use all the bells&whistles, perhaps 1%, but every time this 1% will be different.
Here is an excellent essay to the topic by Richard Noel:
How a V-Accordion Can Alter Your Playing

In the several years that I have owned a v-accordion, Ive realized that I have adjusted to the v-accordion in many ways, and I thought Id share some of these factors with other v-accordionists.
These changes are most relevant for those who think of the v-accordion as an orchestral instrument rather than as an alternative acoustic accordion. When I play the v-accordion as an acoustic accordion, most of these factors are less relevant.
1. Bellows Control. You may have to alter your use of the bellows in order to make the v-accordion sound like the orchestral instruments you are emulating. A one-style-fits-all approach to playing all of the various orchestral instruments just doesnt make sense to me, although I will be the first to admit that it is not easy to change ones techniques according to the emulated instrument. Sometimes you need to accent notes differently, other times you need to keep the bellows softer if you want a particular sound from an orchestral instrument.
2. Touch Sensitivity. It can cause you to be aware of how hard you are pressing notes in order to utilize percussion effects, note-bending effects, and to play velocity-sensitive instruments. Being conscious of how hard you attack notes adds another dimension to how you play the instrument. If you habitually press the accordion keys very hard, for example, you will not be able to effectively use the note-bending feature.
3. Altered Arrangements. It can cause you to change your arrangements to adapt to orchestral instruments. What sounds good on the accordion may not work as well when using orchestral voices, or you may just want to create a more interesting voicing than available on an acoustic accordion. You may also have to alter your accordion arrangements when the v-accordion does not allow you to use a traditional accordion technique, such as the bellows shake (yes, some may be able to do this, but for many of us the bellows shake is extremely difficult on the v-accordion). You may find yourself strumming to create a guitar sound; using vibrato to hold a violin note, etc.
4. Expanded Repertoire. You may enlarge your repertoire to consider playing songs that you would not have thought of without the availability of orchestral voices. Thus Spake Zarathustra, for example is not one that I would play on the acoustic accordion, but it works well on the v-accordion.
5. Other Techniques. You may want to use other left-hand techniques, such as walking the bass, to take advantage of the orchestral bass options. Or learn to play using in a high note mode while comping with the lower notes. Or creating a percussion pattern with the bass that emulates a drummer.
6. Longer phrasing. You can play much longer phrases without fear of breaking the phrase with a bellows change. This of course depends on how you set the bellows controls, but in general it is possible to play much longer phrases. Many v-accordionists appreciate this characteristic.
7. Music Conceptualization. It can cause you to change the way you think about the music you are playing. If Im using a sax, for example, Im thinking how would a sax player approach this piece. Its not just technique, but how you approach songs.
Im sure there are more examples that others can think of. In a way, the v-accordion makes an already-complex instrument even more so. I suppose thats one reason I never seem to tire of playing and experimenting with it. I cannot imagine ever mastering all of the nuances of sound that we can create on the v-accordion, but i enjoy the adventure.
