I have room for only one of each next year and there are so many choices. I've never grown either color but just cleared out a bunch of daylilies so I now have the room. Looking for recommendations.

I know these have been around a long time and may be too common but I suggest Kellogg's Breakfast and it's cousin/sister KBX, the potato leaf version. A fun one to try and get to do well is Orange Russian #117. This is a bi-color heart shaped with excellent flavor if it comes out right which for me is one in three years. With that said, why bother? On a right year it is the best tasting and prettiest tomato you will ever try.

KB and KBX are very large and on the sweet side with excellent production. Great way to start growing orange/yellows.

Taxi is a very mild, round yellow determinate. Jubilee is an old variety, but a good one, and produces deep gold beefsteak style tomatoes. It is a late producer. There is also Lemon Boy, which is related to Better Boy and Best Boy. Ive grown all three and liked them. A nice OP bi color yellow is Pork Chop, by Brad Gates. It's another beefsteak style, and has hints of citrus. Delicious!
Pork Chop, on the vine and picked.

Thank you both Paul and Lynda. This has been a wild tomato season for me. I was at a restaurant in New York a few years ago and they served an heirloom tomato salad that was fabulous. So I started buying heirlooms which are $3.99 - $5.99 lb here. The orange and yellow are getting harder to find and so are the plants.

I have donated a lot of my daylilies and decided to try growing the tomatoes.
I started seeds and just as the plants were starting to flower I came home one night to find a deer prancing down the driveway, probably an escapee from the state park up the road. .
The next day I found that it pranced right through my plants out back. Went to a nursery and bought plants. I wasn't paying attention that Pink Brandywine was indeterminate and it grew almost 9 feet tall and as wide as an overgrown bush which took up more space than I had planned. Next issue was tomatoes on Mortgage Lifter never growing more than 3" so I ripped the plant out. My most perfect tomato is huge and flawless. Huge meaning about 1.75 lb and I don't know the name of it as I'm pretty sure the Boxcar Willie tag is incorrect.

I was cleaning out the shed and found a bottle of Neptune fish fertilizer with a tiny bit left , mixed it and sprayed the daylilies and tomato plants. Next day I find tomatoes with nibbles from raccoons attracted to the fish smell. Hopefully my neighbors were all indoors the next day when it was a 97 degree day and the air smelled like dead fish.

It's all been a joke a minute.

Sounds like it! I do use fish fertilizer, but don't pour it over the plants, but put it at the base. I have a lot of feral cats…… I don't have any deer issues, thank goodness! My emmies are stink bugs, hornworms, fruitworms and diseases. Diseases are really bad here.
It sounds like you would rather have determinate over indeterminate plants. Key to doing that is to look closely on the tag. If the tag doesn't say, then go home and look them up.
I've been growing tomatoes about 22 years straight now, so I've gotten up a list of what does well here. So will you. I encourage you to try new ones every year, if you have the space, and that way you can find what you like AND what grows well for you. I think descriptions in catalogs and tags are pretty useless…. Tomatoes are affected by your own personal climate and soil. What does well for me might not do well for you. Good luck planning for next year!
