I have used drip for years. I get my supplies from Dripworks. I just compared them to Mister Landscaper. DW has a much more extensive inventory and is much cheaper. DW has been wonderful to work with.

You need 1/2 mainline and then run your emitters to the rose/plant on 1/4. Making your mainline a closed system maintains even pressure. I am less precise than I should be, but I have hundreds of roses. I just put everyone on 1-gallon emitters for 45 minutes twice a week, on the timer. If it's super hot, I'll make it 3x a week, if it rains sufficiently, once a week. Get in the habit of checking your emitters a couple of times a season.

I changed from watering my roses with a hose and sprinkler, to a drip system around 2 years ago. The difference was profound! You can see exactly how large the plants were when I switched, as the branches that developed during the sprinkler days had smaller leaves that were closer together. Many of the plants grew to 4 to 7 feet in a single season. The flowers are larger too. The application of water through drip irrigation allows the water to penetrate much deeper into the soil. If you just water on the surface, you will have a plant with a shallow root system.

I use a 1/2 inch line to each rose. I install a barbed "T" that is compatible with 1/4 inch line. I then install a 5 foot piece of 1/4 inch line that has emitters embedded every foot to the barbed "T", creating a loop around the rose plant. The water is applied around the plant evenly through the 5 embedded emitters. I get my 1/2 inch tubing in 1000 foot rolls at a local irrigation supply house (I live in a rural area and the prices for this is very reasonable). I get my 1/4 inch tubing with the embedded emitters from www.mrdrip.com. I got a 1000 foot roll (enough for 200 roses) for around $75. I also got the barbed "T"'s from them.

I live in Las Vegas Nevada and have about 60+ roses, 20 fruit trees, 20 shade trees, vegetable garden ect... on a 1/2 acre. I use 2 drip stations in th front and 4 drip stations in the back. We also have a motor home and travel for months at a time and have not lost a plant in about 6 years. Let me share a few things I have learned.

1. Don't skimp on 1/2 inch tubing. Never run the 1/4 inch tubing longer than 30" shorter is better.

2. I use Rain Bird emitters that stick in 1/2" tubing and then the 1/4 tubing runs between the emitter and the plant. They are made for this item #XB20PC. This way you don't have pressure on the 1/4" tubing. The 1/2" tubing is all buried under 3" of dirt. This helps with the emitter coming off because of water pressure, heat of the sun, cold of the winter and just the age of the tubing.

3. Every plant has at least 2 emitters. If one gets stopped up or doesn't work your plant hopefully will still live. Instead of having only 1 water source you coming out and checking the plant and it has had no water and is dead. It will be struggling with 1/2 the water but your plant will have a chance. You also encourage the roots to spread out. The best way to look at it is roots will not grow where you have no water. So, it's like potted plants all over your yard underground. If you increase the pot size the plants will grow bigger.

4. I always use the same size emitters. That way I know that all my emitters are emitting the same amount of water. Trees and large bushes have more emitters my roses have 2 emitters. You can use less or more water by running for longer or shorter times.

I have never used these systems you are asking about. I buy the items separately at Lowe's, Home Depot, and are local nursery Star. I like the Rain Bird Emitter the best.

Dripworks is not a 'system,' just a supplier of compatible parts. Most of Rain Bird parts work with theirs. I went to Dripworks when I moved to the east, which believes it gets enough rain, so HD, Lowe's etc don't carry drip parts here. I like both M-R's two-emitter system and John's 1/4 embedded emitter circle, tho I haven't had any problems with my single emitters. But last fall my parrot chewed off half my emitters--he was 'helping' in the garden--so as long as I have to do repairs, I might as well upgrade. I have six stations for 425 roses.
