Hi there and welcome to the forum
Assuming that the IP you have chosen to represent you has given you advice on all of the solutions available to you, including the advantages, disadvantages and implications of each one - only you can decide which one better suits you.
With no assets at risk from bankruptcy, the key decider in my opinion is deciding whether you wish creditors to be repaid some money - in which case an IVA is a better solution - or if you do not care whether they are repaid or not - then bankruptcy is quicker and cheaper for you.
Please note that student loans cannot be discharged under bankruptcy proceedings.
