Sure.
This is my personal opinion only and does not reflect the experiences of others.
I assume your main goal with these is to raise vibration, right?
VoC:
First 2 days my body was shaking, it was an interesting experience, kinda shaking off negative energy from my system. Afterwards it always felt like gently being vibrationally lifted up. You can get a slightly weaker similar effect by looping Raise Your Vibrational State, which is free.
Do not buy this if you want to focus on manifestation.
Every field that raises your vibration will indirectly enhance your personal manifestation ability.
VoDL:
It feels like VoC with a slight edge of love added into it.
As if I would play VoC + Attract More Love Into Your Life at the same time.
I rarely use this field because the love aspect for me in this one is not strong at all.
I would rather play some angels fields for that.
VoT:
Similar to VoC but with Ego Dissolution included.
Because of this, this field feels more liberating for me than the others and I can sense the unity of existence much more directly.
All 3 raise your vibration.
VoT has Ego Dissolution in it, which means you get 2 effects by listening to one field.
If you want to buy one of these 3, I recommend getting VoT.
If you want to raise your vibration in general, go for a combo of the free fields mentioned in this thread + Ascension-naut NFT.
Also read the Ascension tag thread.
