SELT Test Centre options for Tier 2 Skilled worker

I could see 4 options for SELT for Skilled Worker Visa

IELTS SELT Consortium,
LanguageCert,
Pearson,
Trinity College London

Does anyone have an opinion of which one is better/easier than others. I was thinking of doing Trinity College SELT and if anyone have any views please let me know

Hi,
LangCert is better of all for couple of reasons
1. Exam format and instructions are simple and clear
2. Frequent exam dates are available
3. Sample papers are available for free
4. Customer care is responsive and helpful

Note: I have purchased SELT examz available with me which is not needed for my wife anymore. I can offer that to you if needed. contact me on personal contact information removed by moderator
