Is there something better than Inkscape?
It depends what you mean by better. If your main issue with Inkscape is that "it's not intuitive to use and [you] waste time to do simple things", then there are tools that have fewer features, but are more intuitive to use.
Personally, "simple things" for me sounds like inserting simple shapes, images and text. If that's not what you mean by "simple things", please edit your question to add more specific requirements.
Google Slides
Weirdly, Google Slides can be used to create "simple" SVGs. It has the advantage to be free and no installation is needed.
Simply create your SVG and use the option: Download > SVG
For quick and simple things, that seems like a reasonable option with a relatively intuitive interface.
PowerPoint
Even though it's not free, I'm going to include this as well since you might already have it on your computer and/or it might be something you have access via a work or school subscription.
Just like Google Slides, PowerPoint can export your slides to SVG, it is an option to consider for simple SVGs production.
It even supports exporting all your slides as SVG natively unlike Google Slides which requires the use of a script that you paste in the developer console to export all selected slides.
Regarding the ease of use, PowerPoint has an intuitive and familiar interface, so if that's your main criteria, it has you covered.
Note that the online version of PowerPoint is free, but doesn't support exporting your slides to SVGs as far as I know.
