Redoing our old in ground pool

I had many people come out to give their bids and thought this would be great but now it leaves me confused.

Our plaster is chipping and peeling and has never been redone and it is over 30 years old and we have owned it for 20 years.

I thought I would like Pebble tec but it is rough and for little kids I think it would be hard on their feet. Today I saw Glass I think the name is Jewel it is costly but seems to be great. We plan on taking the plaster down to the metal and then having new plaster and either glass or Pebble tec.

We live near the beach and wondered how good these are and especially the glass Jewel. What about the moss would it stick?

Then of course we need to buy a new heater and wondered is it cost effective and would it be expensive to run if we want to swim? Our pool holds 40,000 gallons of water, 107 in measurement, called a Lazy L Shape. Yes it is very big.
I don't want to spend a lot yet I want it to last and be pretty to look out into the yard and have it pop.

Please Advice.
Thanks
