Hi, is it better to have the service providers, i.e., rockwills, maybank trustee, rhb trustee as sole executor for my wills or best to nominated one of my beneficiaries as executors? pro and cons for each option?

To save on the estate administration charges?

one of the wills writing service provider informed me the estate administrative process will take 1-1.5 years for simple estate case like mine? Need to take so long?

My assets are not complicate with only a house, share trading/ unit trust investment accounts, vehicle and some banks accounts.
