Unless you are applying to firms who are recruiting for training contracts starting in 2025, I would apply for the SQE.
For the firms recruiting for 2026/2027/2028 training contracts, there will be a very small pool of candidates who are eligible for the LPC and so many firms are moving to the SQE (if they have not moved already).
The LPC training contract has more restrictions and regulations - you have to be a recognised training provider, you have to see three distinct areas of law, you have to do the PSC, you have to have a Training Principal. All of those things are not needed in the SQE training contract, and so firms and employers prefer the SQE because of its flexibility and freedom.
If you were to do the LPC, you may find you still end up having to do SQE2 anyway where firms are not offering LPC training contracts any more.
