Back in the day, I resisted live plants for a long time but sometimes an ole dog can learn new tricks....
I once had a collection of plastic plants in my 60g display tank and about once a month they went through the dishwasher with either some white vinegar or some bleach. Rinsed well, they went back in 'fresh and new looking.
But artificial plants come with a curse and mine are now locked away harmlessly in a bin somewhere.
First artificial plants just don't look real and I'll bet the fish aren't fooled either. Now if you have colored gravel, Sponge Bob, a deep sea diver, a treasure chest and/or a sunken ship...well maybe it doesn't matter! But if your target is underwater realism, it does.
Second, unlike living plants, they do nothing to improve water quality. Living plants use nutrients (aka pollution) to grow, converting them into plant tissue we later remove by trimming. This is especially true for fast growing stem and floating plants. And the beauty of floating plants is that they tend to do well with almost any lighting while rooted plants may need higher intensity.
So I finally came around, bought a better light and began a planted aquarium. Now it's low tech to be sure although for a time, I toyed with DIY CO2 (sugar water and yeast) and the plants did well, but that got old. I do use some modest fertilizer just to ensure the plants get everything they need.
Okay then, back to artificial plants, if you must, I tend to agree with
@Bruce Leyland-Jones that silk plants look better than plastic and because they're softer, are likely more fish friendly (although the fish will probably still know the difference!)
